Radar Mast & Final Assembly of Yacht

DESIGN OF A SUNSEEKER YACHT

OBJECTIVE:

The objective of the project is to design and model all the parts of an Sunseeker Yacht and assembling it to create the Photo Realistic rendering of the yacht in which the sketch should be fully defined and the mates in assembly should be fully constrained. Rendering done by using PHOTOVIEW 360 and SOLIDWORKS Visualize Professional. Proper decals, cameras, lights and appearances should be added before rendering.

INTRODUCTION:

Solid works is a solid modelling computer-aided design (CAD) and computer-aided engineering (CAE) program published by Dassault Systems.

Solid works has three basic environments namely: Part, Assembly and Drawing.

In part modelling we will be using parameters include numerical values such as lengths, diameter/radius as well as geometrical components like tangency, collinearity, parallel, concentricity, vertical, horizontal etc. Converting 2d sketches into 3D models require feature-based approach. some of features are extrude boss, extrude cut, revolve, revolve cut, shell, loft, sweep, hole, fillet, chamfer, slot etc.

Assembly, in this environment the mates determine the final assembly and relation of various parts to each other.

Drawing, environment is mainly used to create 2D sheets with all main views of the solid parts and assembly.

File formats in Solid works: Parts: (. SLDPRT)

Assembly: (. SLDASM)

Drawing: (. SLDDRW).

SOLID MODELLING:

Solid modeling (or modelling) is a consistent set of principles for mathematical and computer modeling of three-dimensional solids. Solid modeling is distinguished from related areas of geometric modelling and computer graphics by its emphasis on physical fidelity.

Surface Modelling:

Surface modeling is considered a more complex technique for displaying objects than wireframe modeling. Surface modeling has much less ambiguous display functionalities compared to wireframe modeling, but not as much or sophisticated as solid modeling.

DESIGN PROCESS:

The design process involves the following steps:

• Identifying the model requirements.
• Conceptualize the model based on the identified needs.
• Developing the model based on the concepts.
• Analyzing the model.
• Prototyping the model.
• Constructing the model.
• Editing the model, if required.

DESIGN INTENT

In this project, we will be able to sketch and build an entire American Predator Yacht using SOLIDWORKS to understand the 3DModelling methodology of Surface Modelling.

In this project we’ll learn, curve generation, surface creation from curves and sketches, different types of surfaces –

• boundary surfaces
• lofted surfaces
• filled surfaces ruled surfaces- reference planes
• surface trims
• surface knit
• move/copy surfaces
• mirror surfaces etc.

Design methodology:

The following are the key parts/models we will deal with in surface modelling using SOLIDWORKS.

• Modelling of propellers, radar
• Blueprint set-up
• Modelling of the hull, garage door
• Modelling of rear seats, middle seats, front seats
• Creation of the superstructure
• Final assembly model of the Predator Yacht.

Some of important features used for making Yacht assemblies:

Mirror:

Features can be mirrored about a plane or planar face. The mirrored features maintain a relationship with the original features such that any changes to the original features are also made on the mirrored features. A mirror sketch entity is a copy of a selected sketch entity that is mirrored about a centerline.

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.

Sweeps:

Sweeps take a sketch, called a Profile and move it along a Path. It must be a closed, non-self-intersecting boundary. However, the sketch can contain multiple contours - either nested or disjoint. Sweeps can also be used to remove material as a Swept Cut.

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.

Reference Geometry:

Reference geometry defines the shape or form of a surface or a solid. Reference geometry includes items such as planes, axes, coordinate systems, and points.

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.

Split Line:

The Split Line tool is used to project an entity (sketch, solid, surface, face, plane, or surface spline) onto other surfaces or curved/planar faces.

Surface loft boss/base:

Loft surfaces are surfaces generated by multiple 3D curves or existing edges creating a smooth tangency between the selected curves.

Swept Surfaces:

Surface that are generated from a section curve positioned along a path.

Surface Fill:

The filled surface feature constructs a surface patch with any number of sides, within a boundary defined by existing model edges, sketched, or curves, including composite curves.

Trim Surface:

Trim surface is the go-to tool for trimming surfaces and removing information, and is exceptionally easy to use.

Knit surface:

Knit surface is a tool used to combine two or more faces and surfaces into one surface.

Ruled surface:

Ruled surface creates surfaces that extend out in a specified direction from selected edges.

Extend Surface:

This feature is used to extend a surface by selecting an edge, multiple edges, or a face.

PART MODELLING DESCRIPTION:

PROPELLER:

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.

RADAR

Marine radars on ships used to detect other ships and land obstacles, to provide bearing and distance for collision avoidance and navigation at sea. They are electronic navigation instruments that use a rotating antenna to sweep a narrow beam of microwaves around the water surface surrounding the ship to the horizon, detecting targets by microwaves reflected from them, generating a picture of the ship's surroundings on a display screen.

BLUEPRINT :

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 pattern that can be followed. They were easier to read and faster to make.

HULL:

The main body of a ship or other vessel, including the bottom, sides, and deck but not the masts, superstructure, rigging, engines, and other fittings.

GARAGE DOOR

A garage door is a large door on a garage that opens either manually or by an electric motor (a garage door opener). Garage doors are frequently large enough to accommodate automobiles and other vehicles. The operating mechanism is spring-loaded or counterbalanced to offset the weight of the door and reduce human or motor effort required to operate the door. Less commonly, some garage doors slide or swing horizontally. Doors are made of wood, metal, or fiberglass, and may be insulated to prevent heat loss.

FRONT SEAT :

Front seats feature two connected seats that are built back-to-back from one and other. They have a built-in storage unit underneath them. Lounge seats can also fully recline right back to make it easier for you to kick your feet up and get more comfortable. The front seat in our model was placed before the superstructure and also it has sun pads to rest on it. Sun pads are a great way to reclaim lost space on our boat.

MIDDLE SEATL:

The middle seat in our model was placed just behind the superstructure. It is provided with a luxury table to dine out. It can also be used to have casual meetings with co-passengers.

REAR SEAT:

The rear seat was placed at the end of the deck surface. The rear seat consists of locker racks and steel doors for our stairs. The flag was also placed behind the rear seat since it’s the end part of our yacht. To have a nice view from the yacht while having a drink the rear seat was also provided with a slot to rest the glass or mug.

SUPER STRUCTURE:

A superstructure is an upward extension of an existing structure above a baseline called ground level and it usually serves the purpose of the structure's intended use. A superstructure is a decked structure on the freeboard deck, extending from side to side of the ship.

RADARMAST:

A mast is a vertical ship structure mounted on top of bridge and forward of the forecastle towards the ship’s bow. It accounts for the support platform for the ships derrick and hold necessary equipment’s such as radars, navigation light and ships horn in case of foremast. They are made of high tensile steel with added rigidity based on the size of derricks it holds. Other than that, a ships main mast is also used to hoist ships flag. Out of different parts of ship the main job of mast is to hold necessary equipment such as radar receiver, navigation lights, ships horn, flags and derricks in some case.

Assembly:

Combining multiple parts that fit together to create assemblies is called ASSEMBLY in SOLIDWORKS. We integrate the parts in an assembly using Mates, such as Concentric and Coincident. Mates define the allowable direction of movement of the components

Mates:

Mates position the components in an assembly precisely with respect to each other. Positioning the components defines how they move and rotate with respect to each other. Mates create geometric relations, such as coincident, perpendicular, and tangent.

Following are mates of Yacht Assembly.

RENDERING:

Rendering of the Solidworks model is done using PhotoView 360 and Solidworks Visualize.

PhotoView 360 is a visualization and rendering solution included with SOLIDWORKS. Providing a highly interactive environment for viewing designs as well as for creating photo-realistic renderings it can be used to showcase our designs.

SOLIDWORKS Visualize (formerly known as Bunkspeed) provides a suite of standalone software tools that combine industry-leading rendering capabilities with visual design[1]oriented features and workflows, allowing easy and fast creation of visual content that communicates a design's vision, passion, and emotion.

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.

Some of the Appearances used in PhotoView 360:

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 PhotoView 360 can be viewed on the screen or saved to a graphics file.

Here is the image of Decals which are added to Yacht.

Options:

PhotoView 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.

SOLIDWORKS VISUALIZE:

Quickly and easily create professional, photo-quality images, animations, and other interactive 3D content to get your products to market faster. SOLIDWORKS Visualize allows us to leverage our 3D CAD data to create photo-quality content in the fastest and easiest way we can– from images to animations, interactive web content, and immersive Virtual Reality.
