Radar Mast & Final Assembly of Yacht

FINAL ASSEMBLY OF YACHT

1. OBJECTIVE

To use SolidWorks to create a realistic and fully integrated yacht model by designing and assembling every component of the yacht, including the radar mast, hull, garage door, seating, superstructure, propeller, and radar system.

2. INTRODUCTION

In this project, separate yacht components will be designed and put together to create an accurate and useful model. The model was developed using SolidWorks and a variety of advanced CAD tools and rendering procedures. All of the parts are flawlessly integrated in the finished assembly. Solidworks Photoview 360 or Solidworks Visualize are used to render the 3D model.

3.DESIGN METHODOLOGY

The assembly process involved the following steps,

i. Individual Component Modelling

SURFACE BODIES (Hull, Superstructure, Front and Rear Seat)

• Establishing the blueprint.
• Creating constraint sketches based on blueprint references.
• Projected curve formation.
• Surface loft is used to form surfaces from these projected curves.
• Surface extrude, surface fill, surface sweep, and ruled surfaces are some of the features that are used to form other surfaces.
• In order to create a solid body from surfaces, we knit the surfaces together until there are no gaps between them.

FOR SOLID BODIES (Radar mast, garage door, middle seat, and propeller)

• We have utilized the blueprint as a guide for a few solid bodies.
• Constrained drawing creation.
• Utilizing features such as Swept Loft, Cut Extrude, and Boss Extrude.

ii. Assembly

• Using the appropriate mates, all the components are put together in SolidWorks assembly environment.
• Verify whether there is any interference between the components.
• If interference arises, adjust the components appropriately to prevent inter-part interference.

iii. Photo-Realistic Rendering

• The yacht's setup and adjustment to our surroundings.
• Modifying altering materials and colours.
• Decals are added.
• Setting up the rendering scene.
• The configuration of rendering lights.
• The final rendering.

The flowchart below illustrates the design and assembly workflow:

4. DESCRIPTION

4.1. Blueprint Setup

Creating a comprehensive digital layout of the complete yacht is part of the blueprint setup process. This stage guarantees that every part—including the radar and propeller—is appropriately incorporated into the overall design of the boat. With its technical drawings, measurements, and assembly instructions, it acts as the main manual for assembling the yacht.

A high-level plan that directs team members through the process of creating and adding to an open course is called a design blueprint. Its goal is to provide a visual representation of the course's overarching "architecture" that will direct the process of collaboration, design, and development.

We need some sort of reference in order to design and model the yacht. The intended views of the product from all angles (front, side, top, bottom, and back) or some idea sketches could serve as that reference. In the Solidworks environment, we created blueprints of the desired views of a yacht and positioned each view in relation to the others. After that, we designed every component or body of the yacht using this blueprint setup as a guide. We set it up correctly and insert the blueprint views as a sketch.

4.2. Propeller

An essential part of the yacht's propulsion system is the propeller. It must be built to be as efficient as possible on the water, guaranteeing maximum speed, fuel economy, and manoeuvrability.

4.2.1. Design Overview

A propeller is a machine that functions similarly to Archimedes' screw when rotated. It has a revolving hub and radiating blades arranged at a pitch to create a helical spiral. It acts on a working fluid, such air or water, to convert rotational power into linear thrust

4.2.2. CAD Modelling Process

The yacht's propeller is a rotating component attached to the rear of the hull. I used the following features in the propeller.

• Rotate: This function rotates the closed two-dimensional sketch around a central axis.
• Cut extrude: It is employed to cut the portion that has been extruded.
• Revolve: This function is utilized in this section to create a hole over the revolved portion.
• Loft: It's utilized to make the propeller's vanes.
• Pattern: The circular pattern is used to replicate the pattern in a circle.
• Fillet: It is used to give all of the corners a rounded appearance.

4.3. Radar

Without radar equipment, yacht would not be able to spot many of the floating objects in the water. Yacht's radar equipment will notify of other objects in the water that may not be aware of. Yacht can avoid running over a sandbar or reef by using this approach.

4.3.1. Design Overview

Navigation, collision avoidance, and weather monitoring all depend on the radar system. The radar system is represented in the yacht's CAD design as a mix of the housing, mounting structure. The goal is to make sure the radar unit fits correctly into the yacht's construction.

4.3.2. CAD Modelling Process

• Extrude the closed 2D sketch to the desired height using the boss extrude tool.
• Cut extrude: It is employed to cut the portion that has been extruded.
• Fillet: It is used to give all of the corners a rounded appearance.
• The purpose of a sketch pattern is to pattern features at a sketched spot.
• Mirror: By using the mirror face as a reference, it is used to mirror the body.
• The purpose of the spittle line is to cut the face into pieces. This capability allows the text to be printed over radar.
• Text: Using the split line command, this 3D text will be written across the radar.

4.4. Hull

Marine boats hulls serve as its structural core and are in charge of buoyancy, stability, and hydrodynamic performance. To maximize watercraft efficiency, the design strikes a compromise between strength, weight, and fluid dynamics.

4.4.1. Design Overview

The watertight body of a boat or ship is called a hull. The hull may have a deck covering it entirely or in part, or it may open at the top. A deckhouse and additional superstructures like a funnel, derrick, or mast may be located at the top of the deck.

The base of a yacht is called the hull. Its many surface characteristics aid in the construction of this part's intricate shapes. The entire surface portion was then turned into a solid using the merge and knitted option.

4.4.2. CAD Modelling Process

The base of a yacht is called the hull. Its many surface characteristics aid in the construction of this part's intricate shapes. The entire surface portion was then turned into a solid using the merge and knitted option. The hull model was created using surface and solid modelling techniques. Key steps included:

4.6. Front, Rear, and Middle Seat

4.6.1. Design Overview

There should be enough of seats on the hull for passengers to enjoy the surroundings because the Predator yacht is known to be a sun-seeker. There will be seats on the yacht's front, centre, and back in consideration of this demand. The ergonomics of the yacht are reflected in the design of these seats. The middle seat is typically part of the social or lounge area of the yacht, providing comfortable seating for passengers during leisure or dining activities. The rear seat, often located in an open-deck or recreational area, is designed for maximum seating capacity and durability under outdoor marine conditions.
