Radar Mast & Final Assembly of Yacht

 

MODELLING AND ASSEMBLING OF SUNSEEKER PREDATOR YACHT :

Objective:

The main objective is to produce a detailed model of different parts of yacht with the help of blue prints and some given dimensions, and assembling the entire model.

Introduction:

• Solid works software is a mechanical cad software which helps the designers to show their idea of a part or model in a realistic view in a virtual representation without actually producing a real part, which is so helpful to make corrections or to make new changes in the model easily before making a physical part product.
• In the process of modelling a sun seeker predator yacht we design a part or model by using initial 2D sketches, and then we turn them into 3d models using the tools like surface tools, featuring tools etc.
• Assembling and visualization plays an important role in any model that we create in a cad software.
• Here almost 90% of the model is modelled using surface modelling and the we make them into a solid body.
• Most of the part bodies are modelled using blue prints only.

DESIGN METHODOLOGY/DESIGN APPROACH:

 

 

TYPES OF COMMANDS :

Sketch-

Create the sketches and decide how to dimension and where to apply relations.

Features-

Select the appropriate features, such as extrudes and fillets,determine the best features to apply, and in what order to apply those features must be decided.

Surfaces-

Surfaces are a type of geometry that can be used to create solid features,

Assembly-

Select the components to mate and apply the mates.

1.SKETCH-

Creating a model usually begins with a sketch. From the sketch, we can create features. We can combine one or more features to make a part. Then, we can combine and mate the appropriate parts to create an assembly. From the parts or assemblies, we can then create drawings.

3-D SKETCH -

When sketching in 3D, we can snap to the major directions, X, Y, or Z. and constraints are applied Along X, Y, Z respectively. These are constraints to the global coordinate system. When sketching on a plane, we can snap to the horizontal or vertical directions in the plane, and constraints are applied to the Horizontal and the Vertical. These are constraints to a plane, planar face, etc.

SKETCH COMMANDS:

Smart Dimension - Creates a dimension for a selected sketch entity.

Line –

 Line is one of the first sketching tools in Solid works Sketch Command Manager which can be drawn horizontally, vertically or at any angle. It plays very important role to complete the 2D drawing of the product or part and very easy to utilize its features.

Circle –

 The circle is another important sketching tool which enables to create the circular drawing on the graphics area. There are two circle tools are available and they are "Centre circle" and "Perimeter circle.

Rectangle-

Sketches rectangles or square with a centre point at a selected angle. Parallelogram sketches a standard parallelogram. Spline - A 20r 3 dimensional curves defined by a set of control points.

Points within a spline can be added or deleted. Sketch Fillet - A tangent arc in between two sketch entities can be created.

Point –

 Inserts a point or vertex into a sketch entity. This cannot be deleted if it is part of sketch endpoint or centre point. Text - It can be used to write the text necessary wherever required either it's a plane or face.

Offset Entities –

Copy a sketch entity to a specified distance from the original entity. Must have a sketch entity already drawn and selected to use this tool.

Sketch Picture –

 Insert an image file into the background of a sketch. This allows the user to 2D sketches based off of the image. Use the sketch picture property manager to alter the inserted image.

Convert Entities-

Convert Entities enables you to copy model edges into your active sketch. These sketch elements are automatically fully defined and constrained with an On Edge relation. Convert Entities is like Offset Entities except that the offset distance is always zero.

2. FEATURES:

Some sketch-based features are shapes such as bosses, cuts, and holes. Other sketch-based features such as lofts and sweeps use a profile along a path. Another type of feature is called an applied feature, which does not require a sketch. Applied features include fillets, chamfers, or shells. They are called "applied because they are applied to existing geometry using dimensions and other characteristics to create the feature. Typically, we create parts by including sketch-based features such as bosses and holes. Then we add applied features. It is possible to create a part without sketch-based features.

FEATURE COMMANDS :

Extruded Boss/Base –

One of the oldest commands in the SOLID WORKS software is the boss/base extrude command. An Extruded Boss/Base feature will allow us to take a 2D sketch and add thickness to it in the third dimension.

Extruded Cut –

It's a tool to remove material by projecting a sketched section normal to the sketching plane.

Split –

Lines are used to divide model faces into two. Split lines are created like any other sketched feature. They can be one or  more  connected sketch entities. They must be oriented so that they will pass. Through   model faces when projected normal to the sketch plane. Dome-It can add one or more domes to the selected planar or non planar faces. The software calculates the distance using the radius of the arc as a basis for the dome.

Pierce Relationships –

 The Pierce relationship is used in sweeps. It can be thought of as a 3D Coincident relationship. In our spring, the circle will follow the helix Think of the helix as a thin piece of wire and the profile sketch as being drawn on a piece of paper. If we stick the wire through the paper at the centre of the circle, this would be a pierce relationship. When we perform the sweep, the paper will slide along the wire, held at the pierce point.

Project Curve -  

Select Bi-directional to create a projection that extends on both sides of the sketch. The curve can be used as a path for a sweep.

Composite Curve –

We can create composite curves by combining curves, sketch geometry, and model edges into a single curve. Composite curve can be used as a guide curve when creating a loft or a sweep.

3.SURFACE MODELLING :

Surface modelling is a method of creating planar or non-planar complex geometry which has zero thickness zero thickness geometry is known as surface. The surfaces are generally used to create models of complex shapes. We can convert surface models in solid models. We can also extract a surface from a solid model using the tools available for surface modelling

Modelling of Surfaces:

Surfaces give mush more flexibility when creating complex shapes that cannot be done using solid features. Surfaces can be used to build a shape face-by-face rather than all at once. Surfaces can be used as reference geometry.

• Surfaces can be more efficient than solid features depending on object.

SURFACE COMMANDS:

Lofted Surfaces-

Creates  a lofted surface between two or more profiles or sketches. Specify start and end constraints and add guide curves to control the path shape.

Boundary Surfaces-

The boundary surface feature lets us to create surfaces that can be tangent or curvature continuous in both directions (all sides of the surface). In most cases, this delivers a higher quality result than the loft tool.

Extruded Surfaces –

 Extrudes a sketch or selected sketch contours in one or two directions two create a surface features.

Revolved Surfaces –

Revolves a sketch or selected sketch contours around an axis to create a surface features.

Swept Surfaces-

It Sweeps a closed profile along an open or closed path to create a surface feature. It uses a tangent plane at the end of the path so that the path is normal to the swept surface.

Filled Surfaces-

Patches  a surface within a boundary defined by edges, sketches, or curves. We can use constraint curves to fill surfaces and adjust resolution control to improve surface finish.

Ruled Surfaces-

Inserts ruled surfaces in a specified direction from edges. Tangent to surface, Normal to surface, tapered to vector, perpendicular to vector or sweep can be selected. We can also trim and knit the surfaces and remove any connecting surfaces.

Trim Surface-

It trims the surfaces where a surface intersect with another surface, a plane or a sketch

Knit Surface-

It combines two or more adjacent, non-intersecting surfaces into a single surface body. The surfaces must joint at an edge. If the resulting knit surface encloses a volume, we can create a solid body from the Property Manager

Move/copy surfaces –

Moves or copy surfaces about a plane or a sketch

Offset Surface-

Offsets surfaces using one or more contiguous faces. This tool helps us to create an offset surface with gaps.

Extend Surface-

Extends one or more edges or faces on a surface, based on end conditions and extension type.

Mirror surfaces –

 A mirror feature is a copy of a selected feature, mirrored about a plane or planar face. A minor sketch entity is a copy of a selected sketch entity that is mirrored about a centerline. If the original feature or sketch is modified, the mirrored copy is updated to reflect the change.

Reference plane-

We can create planes in part or assembly documents. We can use feature, and so on.

Projected curve-

A projected curve is typically used either in sweeps and lofts as planes to sketch, to create a section view of a model, for a neutral plane in a draft path or guide curve. There are two types of projected curves:

Sketch on Sketch:

 Use two sketches to make a single curve. Sketch on surface: Use a sketch to project on a surface.

Split line-

The Split Line tool projects an entity (sketch, solid, surface, face, plane, or surface spline) to surfaces, or curved or planar faces. It divides a selected face into multiple separate faces. We can split curves on multiple bodies with one command.

Split point-

We can split a sketch entity to create two sketch entities. Conversely, we can delete a split point to combine two sketch entities into a single sketch entity. Fillet-A fillet is an internal rounding of a corner or edge in a sketch, or an edge on a surface.

PART MODELLING DESCRIPTION:

BLUE PRINT SETUP:

A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets. A blueprint is a guide for making something, it's a design or pattem that can be followed. They were easier to read and faster to make.

 

The above shown Blueprint was used to model the Yacht in a fully defined constraint. For setting up the Blueprint the Sketch pictures options were used and placed the different blueprints at the required planes.

1.PROPELLER :

There can be one, two or three propellers. It is the most important part of the ship without which a ship can't move. So, the main function of propeller is to propel the ship in the forward direction by producing thrust on water. Its working principles are Newton's third law of motion and Bernoulli's theorem.

3.HULL:

A hull is the watertight body of a ship or boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. The line where the hull meets the water surface is called the waterline. The hull of a ship is the most notable structural entity of the ship. To define the hull, it can be said that it is the watertight enclosure of the ship, which protects the cargo. machinery, and accommodation spaces of the ship from the weather, flooding, and structural damage. The hull is a watertight body of a vessel which may be open or may be partially covered with a deck. Hull has several watertight decks and bulkheads as the major transverse membrane.

 

 

 

 

 

 

• The intermediate member of the hull consists of girders, webs and stringers. Depending on the structural arrangements, there may be longitudinal members for strengthening purpose.

ASSEMBLY:

An assembly is a document in which parts, features, and other assemblies (sub-assemblies) are mated together. The parts and subassemblies exist in documents separate from the assembly. For example, in an assembly, a piston can be mated to other parts, such as a connecting rod or cylinder. This new assembly can then be used as a sub-assembly in an assembly of an engine. The extension for a SolidWorks assembly file name is SLDASM.

 

 

 

 

 

ASSEMBLY COMMANDS:

• Smart Mate-A Smart mate is an assembly mating relation that is created automatically.
• Mate-Amate is a geometric relationship, such as coincident, perpendicular,tangent, and so on, between parts in an assembly.
• Mate group - Amate group is a collection of mates that are solved together.The order in which the mates appear within the mate group does not matter.
• Sub-Assembly - A sub-assembly is an assembly document that is part oflarger assembly. For example, the steering mechanism of a car is a subassembly of the car.
• Insert Components -We can insertmultiple instances of the group of components without closing the Property Manager.

 

ASSEMBLY PROCEDURE:

 

Import all the parts manually by using Insert Components option

 

• Then fix the Hull part by applying the coincident mate to the Top, Right and Front planes of the Assembly and Hull respectively.
• Then for each part apply the necessary mates required by the Blueprint using Coincident mates. Angle Mates Distance mates etc.

Advanced mate was also used wherever required.

PHOTO VIEW 360:

Photo View 360 is distinguished from Real View in that it is not a process of the GPU. and photorealistic renderings can be achieved regardless of the graphics card used. This is because it is entirely calculated on the CPU on your PC and is rendered in a sequential event and is therefore not dynamic. Photo View 360 renderings are more photorealistic than Real View because light rays and reflections are more accurately calculated.

Photo View 360 rendering supports:

 

• Self-reflection (reflection of objects in one another)
• HDRI (environmental) lighting.

 

Appearances

Appearances control the way the surfaces of the model look. They can be applied at the assembly, part. body, feature or face of a model. All surface of a model have an appearance applied to them.

 

Materials vs Appearances

Appearances are different from materials. When we applied a material to a part, it defines the physical properties of the part such as density and strength. Included in the material definition is a default appearance, however this can be changed. As an example, if we were modeling a body component for an automobile, the material would be steel, however the final component would be painted, so the appearance could be something other than what was applied with the steel material.

Photorealistic Rendering

Photorealistic rendering is the process of photography except that we are using a computer model instead of a physical model. Prior to actually producing a product we may need to show the customer what the product will look like or we may need to produce marketing materials.

The Photo View 360 software

Photo View 360 is a software solution from Solid works, fully integrated into the Solid works software to create photorealistic images directly from Solid works models. Renderings may be created from Solid works parts and assemblies, but not drawings Photo View 360 can produce photorealistic images to add visual impact to presentations and documents.

Some of the key features of Photo View 360 are:

 

• Photorealistic images directly from Solid works models
• Photo View 360 interacts with the 3D geometry created with the Solid works software. All changes to Solid works models are accurately represented in the Photo View 360 images.
• Fully integrated into Solidworks. PhotoView 360 software is supplied as a Solidworks add-in.

Appearances in PhotoView 360

Appearances affect the way a surface reacts to light. They may be applied to parts, features or faces Appearances are of two general types,

Procedural Appearances

Procedural appearances are defined by some procedure and consist of one or more colors and the way the appearance reacts to light. Procedural appearances can be thought of as 3D, that is they go all the way through the part. This is like adding dye to a plastic to be injected; the color will go all the way through the finished part

Texture Appearances

Texture appearances are applied like wallpaper. During application, they can be stretched, shrunk, rotated, and reoriented to make them fit the surface. The pattern will be duplicated as many times as necessary to cover the entire surface.

Lighting

Lights may be added in the same way a photographer adds lights when taking photographs, PhotoView 360 uses the same lights as SolidWorks but also uses lighting from the rendering environment or scene. PhotoView 360 has the sophistication to trace light rays and reflections.

Scenes

Each SolidWorks model is associated with a PhotoView 360 scene, for which you can specify properties such as environments and backgrounds Scenes help to put products in context.

Decals

Images, such as company logos, can be applied to models.

Output

The rendered output from PhotoVlew 360 can be viewed on the screen, or saved to a graphics file.

Options

Photo View 360 has its own options. Options allow you to customize the PhotoView 360 settings to reflect your preferences. Options are divided into Output image Settings Render Quality, Bloom, Contour Rendering and Direct Caustics

Scenes

PhotoView 360 scenes are made up of the things we see in the rendering that are not the model. They can be thought of as a virtual sphere around the model. Scenes are composed of backgrounds, foreground effects, and scenery, PhotoView 360 has numerous predefined scenes to make initial renderings quick and easy.
