MODELLING AND ASSEMBLING OF SUNSEEKER PREDATOR YACHT

Objective:

The objective is to make detailed models of various parts of a yacht and assemble them to make a yacht model.

Introduction:

Yacht.

A yacht is a sailing or power vessel used for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a yacht, The term, yacht, originates from the Dutch word jacht (which means "hunt"), and originally referred to light, fast sailing vessels that the Dutch Republic Navy used to pursue pirates and other transgressors around and into the shallow waters of the Low Countries.

2. Solid Works

The SOLIDWORKS CAD software is a mechanical design automation application that lets designers quickly sketch out ideas, experiment with features and dimensions, and produce models and detailed drawings.

Design Methodology:
The method for designing the yacht is as follows
1. Designing of parts and their appearance.
2. Assembly of the designed parts of the Yacht.
3. Applying Decals, Camera setup and scene compositions.
4. Final Rendering.

Parts of Yacht:

Propeller
Radar
Hull
Front seat.
Middle seat.
Rear seat.
Garage door.
Superstructure.
Radar master.

Procedure

Propeller

A propeller (colloquially often called a screw on a ship) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft.

Tools Used:

Sketch
Line
Circle
Loft
Rectangle
Revolve
Circular Pattern
Fillet
Extrude Cut

MODELLING PROCEDURE:

The centre portion of the propeller is sketched and revolved.
A reference plane is created for the blades of the propeller.
Create a loft between two rectangles for making the shape of the blade.
Add fillet on the outer surface of the blade created.
Make the centre of the propeller hollow with the help of cut extrude.
Add a fillet to make the edge of the blade smooth.
Now use a circular pattern for making five more blades.

Radar

Radars are X-band or S-band 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.

Radar is a vital navigation component for safety at sea and near the shore. Captains need to be able to manoeuvre their ships within feet in the worst of conditions and to be able to navigate "blind" when there is no visibility at night or due to bad weather. In addition to vessel-based marine radars, in port or in harbour, shore-based vessel traffic service radar systems are used by harbourmasters and the coast guard to monitor and regulate ship movements in busy waters.

Hull

A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck.

Garage door

A garage door is a large door in 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 the 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.

Radar mast

A mast is a vertical ship structure mounted on top of the bridge and forward of the forecastle towards the ship’s derrick and holds necessary equipment such ass radar, navigation lights and ship's horn in case of the foremast. They are made of high tensile steel with added rigidity based on the size of the derrick it holds. Other than that, a ship's main mast is also used to hoist the ship's flag.

Out of different parts of the ship, the main job of the mast is to hold necessary equipment such as radar receiver, navigation lights, ship horn, and derrick in some cases.

Assembly Commands:

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

Assembly Procedure:

Import all the parts manually by using the 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.
The advanced mate was also used wherever required.

Mates

Mates establish geometric relationships between components of the assembly. We define the permissible directions of linear or rotational motion of the components as we add mates. Within their degrees of freedom, we can transfer a component, envisioning the behaviour of the assembly.
