RADAR MAST :

YACHT ASSEMBLY:

REPORT ON YACHT DESIGN:

Aim and Objective:

• To design all the parts of a Yacht under the part modelling environment in SolidWorks separately.
• Assembling all the parts to complete the final yacht design.

And finally, create a realistic photo rendering using SolidWorks Visualize and Photoview 360.

What is Part modelling?

To design realistic models, we need to know about the configurations and positions of all the model parts. Part modelling is designing all the parts of a model separately by keeping some design references useful during assembly. Here all the parts are made in the Solidworks environment.

Parts to be modelled to design Yacht:

• Blueprint setup
• Propeller
• Radar
• Radar-Mast
• Garage door
• Hull
• Front Seat
• Middle Seat
• Rear Seat
• Superstructure

Blueprint setup:

A blueprint is a design or a technical drawing that explains the overall details of the component. It is very useful to design the parts of a realistic model. It shows the specific parts inside a model precisely.

Propeller:

A propeller is a rotating fan-like structure that is used to propel the ship by using the power generated and transmitted by the main engine of the ship. The transmitted power is converted from rotational motion to generate a thrust which imparts momentum to the water, resulting in a force that acts on the ship and pushes it forward. Propeller works based on Bernoulli’s principle and Newton’s third law. In this ship design, three propellers are fitted.

Features/Commands used to design Propeller:

• 2-D Sketch-- A 2-D Sketch consists of a two-dimensional element. It is helpful to make an extrude.
• Revolve-- Revolves add or remove material by revolving one or more profiles around a centerline.
• Cut Extrude—Extrude-cut helps to remove materials from the 3D model. It is just the opposite of extrude boss/base feature because it cuts a sketch profile while extruding. You can cut in both directions and are mainly used for creating holes, channels, slots etc
• Lofted boss/base--Loft creates a feature by making transitions between profiles. A loft can be a base, boss, cut, or surface. You create a loft using two or more profiles.
• Fillet----Fillet/Round creates a rounded internal or external face on the part.
• Circular pattern-- Circular pattern is used to create multiple instances of one or more features that you can space uniformly around an axis.

Design Methodology:

Create 2-D sketches in the selected planes—then use revolve boss/base option to get a 3-D part of the propeller base—then use the loft command to make one blade—then use the cut extrude command to get the appropriate shape of the blade—then use fillet to give fillet at the required location—use a circular pattern to make the other blade—finally give the appearances.

Radar:

Radar is an instrument that can detect surrounding objects using radio waves. So, it helps to detect the location of ships, buoys or birds while sailing on the 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.

Features/Commands used to design Radar:

• 2-D Sketch
• Boss Extrude-- The Boss-Extrude/Base feature will project a 3D model with the selected sketch or face.
• Cut Extrude
• Mirror-- It is used to create a copy of a feature, (or multiple features), mirrored about a face or a plane.
• 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.
• Fillet
• Sketch pattern

Design Methodology:

Create 2-D sketches in the selected planes—use the extrude boss command to create a 3-D part model—then use the fillet and cut extrude base command to create the desired model—use sketch pattern to create screws in the radar part—then use split line option to write text on the modelled part.

Radar-Mast:

Radar-Mast is present at the top of the superstructure. The mast carries radio and radar aerials, signalling equipment (including halyards to hoist flags), navigation lights and an anemometer.

Features/Commands used to design Radar-Mast:

• 2-D Sketch
• Revolve
• Boss Extrude
• Sweep boss/base-- a sweep is a tool that creates a solid, a cut or a surface feature by moving a profile along a path. To create a solid, use the Swept Boss tool to move a profile along a path. The profile can contain one or more closed contours.
• Chamfer-- The chamfer tool creates a bevelled feature on selected edges, faces, or a vertex.
• Fillet
• Mirror
• Curve
• Shell-- The Shell feature hollows out the inside of the solid, leaving a shell of a specified wall thickness.
• Dome-- It creates a dome that is tangent to the adjacent cylindrical or conical face.

Design Methodology:

Create 2-D sketches in the selected planes—then use the boss extrude, fillet and chamfer command to create the base of the radar mast—then use revolve, fillet and dome command to make the radar parts—use the mirror command to make the full structure of the radar mast—then use revolve, dome, fillet and mirror commands to make the two horns-finally give the appearances.

Garage Door:

A garage door is a large door on a garage that opens either manually or by an electric motor. Garage doors are frequently large enough to accommodate automobiles and other vehicles. The garage door is placed here inside the hull to keep automobiles like cars or bikes inside it.

Features/Commands used to design Garage Door:

• 2-D Sketch
• Cut Extrude
• Fillet
• Mirror

Design Methodology:

Part of the garage door is imported from the hull body—then the parent-child relationship must be broken before going further—then use fillet command to give the part a good fillet—then mirror it concerning the side face of the Garage door part—write on the garage door by using text and cut extrude command—then give the part appropriate appearances.

• Surface trim-- Create two or more surfaces that intersect at one or more points or create a surface that intersects with a plane or has a sketch on its face.
• Surface fill-- The Surface fill feature constructs a surface patch with any number of sides, within a boundary defined by existing model edges, sketches, or curves, including composite curves.

Superstructure:

The Superstructure is a part that is present above the deck surface of a ship. The word “Superstructure” comprises two Latin words “Super” and “Structure”. “Super” means “in addition” or “in excess of”, whereas the stem word “Structure” means “to build” or “to heap up”. Thus, superstructure means adding construction to an already existing structure. On the upper part of this, the radar mast and radar are fitted.

What is an Assembly?

An assembly is a document where all the parts, features and sub-assemblies are mated together. Here all the parts of the yacht are inserted one by one and mate with the hull using manual mates. After the assembly, the ship is fully ready for rendering.

Methodology:

Import the hull part first and fix it—then import the other parts one by one—then give the parts appropriate mate such as coincident, concentric, distance mate with the hull—finally, add decals to give it a good look.

Photorealistic rendering:

It is a digital process using a 3-D CAD model within a software package to create a digital image of the model. The result is a rendering image that is hard to distinguish from a photograph of a real-life object.

Methodology:

Use SolidWorks visualize to give a good rendering to all the individual parts and the assembly of the Yacht model.

Conclusion:

All the parts of the Yacht are designed using SolidWorks. After that, all the parts are assembled together using SolidWorks. Finally, scene set-up and camera set-up are done after giving the model a good appearance. The rendering is done using photo view 360 and SolidWorks Visualize software.
