DESIGN OF YACHT

OBJECTIVE:

To Draft and Design the Individual Components of Yacht and assemble it together and render the parts using SoildWorks Visualization.

DESIGN APPROCH:

INTRODUCTION:

Yacht is a sailing or power vessel used for pleasure, cruising or racing. The term yacht originates from Dutch word jacht and originally referred to light, fast sailing vessel.

Yacht consist of following components that are to be designed individually and assembled them together to their proper constraints and mates.

The following components are the parts of the yacht:

1. Propeller
2. Radar
3. Hull
4. Garage door
5. Front Seat
6. Middle Seat
7. Rear Seat
8. Superstructure
9. Radar Mast

Propeller:

Propeller is a device with a rotating hub and radiating blades that are set at pitch to form a helical spiral that when rotated perform an action which is like Archimedes screw. It transforms rotational power into linear thrust by acting upon a working fluid such as air and water.

• For designing the propeller, the main hub is created by simple sketch line and spline drawn on the front plane and extruded using the revolve option around the center line.

• The wings are created by sketching the two different rectangles on two different surfaces and formed into solid using loft option. The shape of the wings are obtained through fillet option.

• For inserting the shaft, the hole is created at the back end of the hub and material is removed using extrude cut option.
• Color is applied to the propeller for appearance as shown in figure.

Radar and Radar Mast:

Radar is a vital navigation component for safety at sea. Marine radars are X band or S band radars on ships used to detect the other ship and land obstacles, to provide bearing and distance to avoid collision. It was able to navigate in blind when there is no visibility at night or due to bad weather.

Here radar is rotating stick which sweeps the incoming microwave signals and radar must contains. The system to produce the outgoing signals using the antenna.

Design of this component involves base creation initially in 2D sketcher and that is being extruded in the feature tab.

The lobes on the two sides as shown in the picture is drawn on a plane which is created with the reference to the mid plane offset at a required distance and using revolve tool solid cylindrical object is formed on the base.

Figure: Radar.

Figure:Radar Mast.

• Revolve:

This tool requires a closed sketch with the central axis which helps to form the cylindrical object is formed on the base.

The antenna are the circular structures where the circle is being sketched or drafted on the base surface initially and extruded in feature tab.

Horns are created on newly created reference geometrical plane and using revolve tool circular horn is formed and the front hollow shape is been developed using shell option.

• Shell:

This tool helps to create the shell to the body which prompts to enter the thickness and reform the solid object into shell type object with the wall thickness as provided.

Hull:

A hull is the watertight body of a ship or boat. The hull may open at the top and it may be fully or partially covered with a deck. Top the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline.

The Design of Hull involves preparation of outer shell surface and the deck surface. The outer shell is drafted with the required curves initially and are extruded and lofted, to obtain the require surface the curves are drawn on different planes and they are projected so that the required curvature is obtained in between the planes.

Figure: Hull.

• Curve Projection:

It is one of the option in solid works tool which gives us the output curve for the two curves/lines drawn on different planes, this is the intersection path where the two extracted surfaces meet.

• 3D Sketch:

Very handy tool to draw any line or curve in space as it is confined to the axis helps to join the projected curves and work on different axis to create geometrical planes.

• Surface Extrude:

It is used to form the surface bodies where the thickness is line thick.

• Surface Loft:

Loft is the option used to prepare very difficult surface formed with the help of 4 different curves drawn on different planes. It involves two profile curves and one or more guide curves.

These lofted or extracted surface which are in intersection are combined together with the help of Surface Knit.

• Surface Knit:

It helps to eliminate the minor gaps exist between the two surfaces and join them together as like a single surface. This option works only for surfaces not for solid bodies.

The handrail present all over the Hull top is first drafted on different planes using the convert Entities option and is designed as shown in the picture and is projected on to the surface of the Hull. These lines are converted into tubes with the help of sweep option which requires a circle at any one of the curves/lines.

• Convert Entities:

It is available in 2D sketching tab which convert the edges of the 3D object to the line projected on to the surface.

• Sweep:

It helps to produce solid tube along the guided curves/line path.

The rope for the anchors is prepared using the option helix/spiral.

• Helix/Spiral:

It is used to create any springs it screw treads as this option contains pitch or height and revolutions which describes how many rings with gap between them.

Thus the half part of the Hull structure is designed and mirrored along the middle plane to form the complete closed structure. Fillets and chamfers are used to smooth the sharp edges.

Garage Door:

Garage is the part is extracted from the hull structure rear part using split entities option and is been saved using different file name and it is edited to fit in the hull a cover or door to the garage space created for storing or equipment’s or vehicles.

This component is designed by using basic 2D sketch in required planes and apply extrude option so that it acquires the required output.

Figure: Garage door.

Seats:

These seats are classified into three groups

1. Front seat
2. Middle Seat
3. Rear Seat

These front, middle and Rear seats are the accessories of the yacht for resting and sitting.

In this design the seats are drawn with reference to the deck surface and blueprint which is been imported into the solid works using sketch tools & sketch picture.

The seat like appearance is obtained with the help of dome option which again consist of continuous option.

Figure: Middle Seat.

Figure: Rear Seat.

Super Structure:

The most complicated part of the whole yacht design is its superstructure which sits on the top of the desk surface.

This super structure also designed with the help of the imported blueprint top, front and side views as shown in the below picture.

Initially the wall of the super structure is created by drawing a line on the bottom plane along with the curvature using the spline option and making it constrained using proper dimensions and being surface extracted in the feature manager tab.

The base wall is trimmed according the estimated design and another surface is extracted with reference to the base wall edge using ruled surface.

• Ruled Surface:

It is used to obtain the extrude surface perpendicular do the plane of reference and the added advantage of ruled surface is that the surface can titled with and angle as prompted in the tool along with the length.

For obtaining the curves at various positions project curve option is used and they lofted together to form the required surface.

During the surface extrusion process unwanted surface are being produced which are trimmed using the Trim tool.

• Surface Trim:

This prompts to select the reference surface and next surface to be trimmed and it also have options to keep the surface or remove the surface that was selected to trim.

After creating all the necessary surfaces from all the sides the surface are being knit option to form a single body and converted in to a solid body.

The conversion of solid body only happens when there is no gaps found between the surfaces that are being extracted and trimmed.

The seats attached to the super structure are extracted out from the line drawn on the mid plane and extruded up to the surface and the appearance created with the help of dome tool as shown below.

Assembly:

All the components are imported into the assembly workbench are according to the tree chart and applied mates to fix their position with respect to the fixed body or object.

Rendering:

Rendering or image synthesis is the process of generating a photorealistic or non-photorealistic image from a 2D or 3D model by means of a computer program. The resulting image is refereed to as the render.

SolidWorks visualize is used for rendering the Yacht, it helps in creating scenes, and also helps in editing the appearance of the Yacht, it also creates the realistic photo image by rendering the yacht model following are the rendered images in different scene.

CONCLUSION:

To conclude, design, assembly and rendering of the yacht are done using SOLIDWORKS. This project has really helped to enhance the skills in surface modelling and product design. It has given me the sensibility how the marine vehicles are designed and a chance to build one.
