YACHT DESIGN

Introduction:

The SOLIDWORKS CAD software is an application for mechanical design automation that helps designers
to easily sketch designs, experiment with features and dimensions, and create models and informative drawings.
A 3D approach to modelling is used by SOLIDWORKS. Since we can design a component, we can construct a 3D model from the initial sketch to the final outcome. From this model, to build 3D assemblies, we can create 2D sketches or fit modules consisting of parts or subassemblies. We can make 2D models of 3D assemblies as well. We can imagine it in
three dimensions when designing a model using SOLIDWORKS, the way the model appears until it is manufactured.

In this report we had discussed about the modelling, assembling and rendering of SUNSEEKER PREDATOR YACHT and included with tools which are used to model the YACHT as well as the quick explanation of each parts.

Design Methodology:

The method used here is Bottom-up designing procedure as follows,

1. Designing of piece parts and its appearence.

2. Assembly of Designed Yacht parts.

3. Applying Decals, Camera setup and scenes compositions.

4. Final Rendering.

The Following parts to be Modelled individually:

  • Propeller
  • Radar
  • Hull
  • Garage Door
  • Front seat
  • Middle Seat
  • Rear Seat
  • Super Structure
  • Radar Mast

Tools Used

Creating a 2D sketch :

A 2D sketch is the base to create a 3D model.It is usually created on the X-axis & Y-axis. This includes lines, circles, rectangles, splines, etc.

Trim :

The trim command is used to remove or erase the extra edges of intersecting lines on a 2D sketch.

Offset:

Adds sketch entities by offsetting faces, edges, curves, or sketch entities to a specified distance.

Convert Entities :

Converts selected model edges or sketch entities into current sketch segments.

Boss Extrude :

It extrudes a sketch or selected sketch contours in one or two directions to create a solid feature.

Extruded Cut :

Extrude cut is a feature which helps to remove materials from the 3D model. It is just opposite to extrude boss/base feature, because it cuts a sketch profile while extruding. It can cut in both directions and mainly used for creating holes, channels, slots etc.

Revolved Cut : Cuts a solid model by revolving a solid profile around an axis.

Revolved Boss : Revolves a sketch or selected sketch contours around an axis to create a solid feature.

Swept Boss :This feature sweeps a closed profile along an open or closed path to create a solid feature.

Loft : The loft feature creates a shape by making transitions between multiple profiles and guides curves thus allowing to create complex geometry with a single tool.

Dome : A dome is a rounded vault forming the outside face of a body or structure, typically with a circular base.

Combine : This feature is used to combine two or more solid bodies together.

Fillet : A fillet is used to connect two adjacent faces using a smooth tangent arc.

Chamfer : The chamfer command is used to connect two adjacent faces using an inclined line.

Surface Extrude :

Using this feature, we can extrude the boundary edges of a face of a solid body or edges of a surface body in a customized direction. A planar surface body is used to extrude its boundary edges.

Ruled Surface : This feature inserts a ruled surface from the selected edges.

Extend Surface : Extends the edge, multiple edges or the face on a surface, based on end conditions & extension type.

Surface Fill : Constructs a surface patch within a boundary defined by existing model edges, sketches or curves.

Boundary Surface : Creates a boundary surface between profiles in two directions.

Lofted Surface : Creates a lofted surface between two or more profiles.

Offset Surface : Creates offset surfaces using one or more contiguous faces.

Surface Trim : This feature is used to trim one or more intersecting surfaces by selecting a cutting edge as the trim tool.

Swept Surface : Creates a surface feature by sweeping an open or closed profile along an open or closed path.

Surface Knit : Combines two or more adjacent, non-intersecting surfaces together.

Shell : This feature removes material from a solid body to create a thin-walled feature.

Mirror : This allows to mirror features, faces & bodies along a face or a plane.

Split Line : Projects a sketch to curved or planar faces, creating multiple separate faces.

Linear Pattern : Patterns features, faces & bodies in one or two linear directions.

Circular Pattern : Patterns features, faces & bodies around an axis.

Projected Curve : This feature is used to project a sketched curve onto a face or sketch.

1. Propeller

A propeller is a type of fan which by converting rotational motion into thrust, transmits power. A pressure difference is generated between the airfoil-shaped blades forward and rear surfaces, and the pressure difference accelerates a fluid (water in this case). Most marine propellers are screw propellers
with helical blades revolving around an approximately horizontal axis or propeller shaft.

Features used

  • Sketch
  • Revolve
  • Loft
  • Cut Extrude
  • Circular Pattern
  • Fillet

2. Radar

Radar is used to detect other ships and land barriers, to provide bearings and distances for the prevention of collisions 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 around the
ship to the horizon, detect targets by microwaves reflected from them and generate a picture of the ship's surroundings on the display screen.A Radar has a flat antenna that spins, emitting a signal, then listening back for that signal. The return signal bounces back at varying times based on what it may be bouncing off of.

Features used

  • Boss Extrude
  • Cut Extrude
  • Sketch Pattern
  • Split Line
  • Mirror
  • Fillet

3. Hull

The hull is the watertight body of a ship or a ship. The hull may open at the top or be completely or partially covered by a deck. The top of the deck can be a deckhouse and other superstructures. The shape of the hull is chosen to strike a balance between cost, hydrostatic considerations (accommodation, loading and stability), hydrodynamics (speed, power requirements, seaway motion and behaviour) and special considerations for the role of the vessel. The hull designing required precise curvature during the sketching stage to avoid any bad geometry from showing up in the modelling stage.

8. Superstructure

Superstructure is an upward extension of an existing structure above a baseline. It consists of the parts of the ship or yacht (in this case) that project above her main deck.
The size of a watercraft's superstructure can have many implications in its performance, since these structures can alter their structural rigidity, their displacements, and/or stability.
It encloses the cabin and living area of the yacht. They are designed in a manner, so that, they add value and hinder the speed and mobility in the least. It was designed after importing the deck surface of the Hull as interface surface. Its designing required precise curvature during the sketching stage to
avoid any bad geometry from showing up in the modelling stage

ASSEMBLY :

As all the parts are designed using solidworks part, now in the Assembly is used to assemble the parts of the YATCH by giving appropiate MATES with required realtive conditions.

YATCH is assembled in the assembly workbench with fix position by the help of applying mates.

RENDERING :

Appearances to the following parts of the YATCH according to suitability shall be added and the following YATCH shall be made in Picture VIEW 360.
The camera setup, the background setup, the backplate and the location of the
yatch rendered and the high-quality final render are specified for the output image.

Conclusion:

  • The parts of the Yacht are modeled. The parts are inserted into the assembly environment and the Yacht is assembled.
  • These are the result of the correct design technique for the simulation and rendering of Yachts in Solidworks using Photoview 360
