PART MODELLING:

Here's a step-by-step guide on how to perform part modeling in SolidWorks:

1. Open SolidWorks: Launch the SolidWorks software on your computer.

2. Choose a template: When starting a new part, you can select a standard template (e.g., millimeters, inches) or create a custom template based on your requirements.

3. Sketching: The first step in part modeling is sketching. Go to the "Sketch" tab and choose a sketching plane (e.g., Front Plane, Top Plane, Right Plane). In the sketch mode, you can create 2D profiles using sketching tools like lines, circles, rectangles, arcs, and more.

4. Dimensioning: After creating the sketch, add dimensions to specify the size and location of the sketch entities. You can use the Smart Dimension tool or other dimensioning tools available in the Sketch toolbar.

5. Geometric relations: To ensure your sketch is fully defined, apply geometric relations (constraints) between sketch entities. Common geometric relations include coincident, parallel, perpendicular, tangent, and concentric.

6. Exit sketch mode: Once your sketch is fully defined, exit the sketch mode.

7. Extrude: Select the sketch you want to turn into a 3D part and choose the "Extrude" tool. Specify the extrusion distance and direction (up to a blind distance or up to a surface) to create a 3D solid from the 2D sketch.

8. Fillets and chamfers: To add rounded edges (fillets) or beveled edges (chamfers) to your part, use the "Fillet" and "Chamfer" features.

9. Additional features: SolidWorks offers various features to modify and refine your part, such as cuts, holes, patterns, sweeps, lofts, and more. Use these tools to create the desired shape and features on your part.

10. Save the part: Once you have completed your part, save the file in the desired format (e.g., .sldprt for SolidWorks part files).

ASSEMBLY MODELLING:

1. Create Parts: Design individual components using SolidWorks' Part Modeling environment. You can create sketches, features, and surfaces to define the geometry of each part.

2. Save Parts: Once you've created the parts, save them separately as individual files with the ".sldprt" extension.

3. Start a New Assembly: Open a new assembly document in SolidWorks.

4. Insert Components: Use the "Insert Component" tool to add the saved parts into the assembly. You can browse and select the parts you want to insert.

5. Mate Components: To define how the parts fit together, use the "Mate" tool to apply relationships between different components. Common types of mates include coincident, concentric, distance, angle, etc.

6. Create Sub-Assemblies: If your assembly is complex, you can create sub-assemblies first and then assemble them into a higher-level assembly.

7. Validate and Review: Check for interferences, collisions, and other design issues within the assembly to ensure it functions as intended.

8. Animate and Test: If necessary, you can create animations or motion studies to visualize how the assembly moves and operates.

9. Document and Communicate: Generate engineering drawings, exploded views, and bills of materials (BOM) to document and communicate the assembly design.

PARTS TO BE MODELLED IN CHOPPER:

• Transmission Belt
• Kick Stand
• Front Fender
• Rear Fender
• Oil Tank
• Chain
• Pedal
• Front Wheel
• Rear Wheel
• Front Fork
• Chassis
• Engine
• Gas Tank

1.TRANSMISSION BELT:

1. Engine power: The engine generates power when fuel and air mix and ignite, creating a controlled explosion that drives the pistons. These pistons, in turn, move the crankshaft, which transforms the reciprocating motion into rotary motion.

2. Power transfer: The transmission belt is connected to the engine's output shaft or the primary drive pulley. As the engine spins, the belt transfers the rotational power to the rear wheel.

3. Pulleys and tensioner: The transmission belt is routed around two pulleys – the primary drive pulley connected to the engine and the rear wheel pulley. The size ratio between these pulleys determines the gear ratio, affecting the bike's speed and torque characteristics.

Features used to create Transmission Belt:

• Sketch
• Offset
• Extrude
• Fillet

Sketch:

            The sketch is a 2D representation of a particular model from different views such as front view, side view, top view, etc.

Offset:

            Offset is used to create a similar sketch at a required distance in the required direction parallel to the sketch.

Extrude:

            The extrude command is used to create a solid extrusion based on the selected sketch or contours. The extrusion made in either a positive or negative direction as required.

Fillet:

            The fillet is used to creating round faces in the interior or exterior corners of the part. The fillet distributes stresses uniformly along the corners.

2.KICKSTAND:

Kickstands are common on many types of bicycles, especially commuter and city bikes, where they are convenient for quick stops and parking. However, not all bicycles come with a kickstand as standard equipment, especially high-performance road bikes or mountain bikes, where weight savings and off-road maneuverability may take precedence.

There are different types of kickstands available, including:

1. Side Kickstand: This is the most common type of kickstand, which extends from the left (non-drive) side of the bike. It typically folds up against the bike's frame when not in use and can be easily deployed by kicking it down with your foot.

2. Center Mount Kickstand: This type of kickstand is mounted to the center of the bike's frame and extends down to the ground in the rear. It provides good stability, especially when the bike is loaded with panniers or cargo.

3. Rear Mount Kickstand: This kickstand attaches to the rear dropout (where the rear wheel axle is connected to the frame) and extends backward. It is commonly used on bikes with rear suspension, where traditional side kickstands might interfere with the suspension.

4. Double Leg Kickstand: This is a more robust kickstand that has two legs extending down from the frame on both sides of the bike. It offers increased stability and is often used for heavier bicycles, cargo bikes, or bikes with child seats.

Features used to create Kick Stand:

• Sketch
• Loft
• Dome
• Extrude Boss
• Extrude Cut
• Fillet
• Split

Loft:

            The loft feature in SOLIDWORKS allows you to generate complex geometry in a single feature. It does this by interpolating surfaces between various cross-sections of a model. These cross-sections can be sketches, faces, or edges. In the loft interface, these cross-sections are considered “Loft Profiles”.

Dome:

            Dome is an architecture, the hemispherical structure evolved from the arch, usually forming a ceiling or roof over the surface/face being selected.

Extrude Cut:

            The extrude cut is used to remove unwanted material from the solid model as per the sketch defined. Based on the sketch the material is removed from the component.

Split:

            Split is used to split a single surface into multiple surfaces based on the sketch, by using the desired sketch split surface can be performed.

3.FRONT FENDER:

1. Splash Protection: The primary function of a front fender is to shield the rider and the bike from water, mud, rocks, and other debris that may be thrown up by the rotating front wheel during wet or muddy conditions. This helps keep the rider and the bike cleaner and enhances visibility.

2. Safety: The fender also plays a role in safety by preventing debris from being thrown towards the rider's face or eyes, reducing the risk of accidents or injuries.

3. Aerodynamics: Front fenders are often designed to be aerodynamic, reducing drag and improving the overall performance and efficiency of the bike.

4. Style and Aesthetics: Besides their practical function, front fenders can also add to the overall appearance and style of the bike. Different bikes may have varying fender designs, which can contribute to the bike's unique look.

Features used to create fender:

• Sketch
• Offset Entities
• Trim Entities
• Revolve
• Dynamic Mirror
• Split

Trim:

            Trim is used to remove unwanted sketch entities or extra portions of the sketch. It works based on some reference points, edges.

 Revolve:

            Revolve is used to create a revolved 3D model using a sketch profile using an axis of rotation. The profile created with the revolution up to 360⁰ axis rotation.

Dynamic Mirror:

            A really quick tip for instantly creating symmetry within a sketch in SOLIDWORKS. As you create a sketch on one side of the centreline, the Dynamic Mirror tool will automatically create a symmetrical shape on the other side, which has the same relations as the sketch you're creating.

4.OIL TANK:

1. Oil Cooling System: Some high-performance or custom motorcycles may have an oil cooling system where additional oil capacity is used to help dissipate heat from the engine more efficiently. These oil coolers can help improve engine performance and reliability, especially during intense riding conditions.

2. Dry Sump System: In rare cases, some motorcycles might be equipped with a dry sump system. In a dry sump system, the engine oil is stored in an external tank rather than the engine crankcase. This design allows for better oil control and can be found in certain high-performance racing motorcycles.

3. Custom Builds: Custom bike builders may create unique designs that incorporate an additional oil tank for aesthetic purposes or to achieve a specific look or theme.

Features used to create Fender:

• Sketch
• Extrude Boss
• Combine

Combine:

            A combine feature is used to merge two or more solids into a single solid.

5.CHAIN:

1. Chainrings: The front chainring(s) are attached to the crankset, which is the set of pedals and cranks. These chainrings have teeth on their edges that engage with the chain.

2. Cassette or Freewheel: The rear cassette or freewheel consists of multiple sprockets of varying sizes mounted on the rear wheel hub. These sprockets have teeth that also engage with the chain.

3. Derailleurs: The front and rear derailleurs are responsible for moving the chain between different chainrings and sprockets. When the rider shifts gears, the derailleurs push or pull the chain, causing it to move to a different gear ratio.

4. Chain Links: The chain is made up of a series of metal links that connect the chainrings and sprockets. Each link has an inner plate and an outer plate, and these plates are connected by pins. The inner plate of the chain is the part that engages with the teeth of the chainrings and sprockets.

5. Power Transmission: When the rider pedals, the chain moves along the chainrings and sprockets, and the engagement of the chain with these teeth transfers the power from the rider's legs to the rear wheel. As the chain moves, it turns the rear wheel, propelling the bicycle forward.

Features used to create Chain:

• Sketch
• Trim
• Fillet
• Extrude
• Patterns

Pattern:

            The pattern is used to create similar geometry or sketch profile up to user-defined instances based on some reference edges, vertex, etc.,

6.PEDAL:

In the context of bicycles, a pedal is a part of the bike that the rider uses to propel it forward. Pedals are attached to the crankset, which connects to the bike's chain and, in turn, drives the rear wheel's rotation. When the rider pushes down on the pedal with their foot, the motion transfers through the crankset and chain, causing the rear wheel to turn and the bike to move forward.

Bicycle pedals come in various designs, including platform pedals and clipless pedals. Platform pedals have a flat surface that allows riders to place their feet directly on them. These are commonly found on casual and urban bikes. Clipless pedals, on the other hand, require special cycling shoes with cleats that lock into the pedal mechanism. This type of pedal is popular among road cyclists and mountain bikers as it provides better power transfer and control.

Proper pedaling technique involves a balanced application of force throughout the entire pedal stroke, utilizing both the downstroke and the upstroke. By doing so, riders can efficiently utilize their leg muscles and improve their overall performance and endurance.

Features used to create Pedal:

• Sketch
• Extrude
• Fillet
• Linear Pattern
• Dome
• Chamfer

Chamfer:

            The chamfer is used to create beveled features on the selected edge face and vertex according to angle or distance specified. 

Linear Pattern:

            Linear Pattern is used to create a similar sketch or feature along a specified linear vector i.e., XYZ directions. The pattern is created based on the reference edge, face, etc.

7.FRONT WHEEL:

1. Size: Front wheels come in various sizes, commonly ranging from 20 inches for small children's bikes to 29 inches for larger adult mountain bikes. The size affects the bike's overall ride characteristics, including stability and maneuverability.

2. Axle: The front wheel is attached to the bike frame via an axle. It is secured in the fork, which is a part of the bicycle frame that extends forward from the headset.

3. Bearings: The front wheel contains bearings that allow it to rotate smoothly around the axle, reducing friction and enabling efficient movement.

4. Tire: The front wheel is fitted with a tire, which is typically made of rubber and provides the necessary traction on various surfaces.

5. Rim: The outer edge of the front wheel is called the rim, which holds the tire in place and provides support for the spokes.

6. Spokes: Spokes are thin metal rods connecting the rim to the hub (center) of the wheel. They help distribute the weight and forces evenly, providing stability to the wheel.

7. Quick Release: Some modern bikes have a quick-release mechanism on the front wheel, allowing riders to easily remove and install the wheel without using tools. This feature is handy for transportation and storage.

8. Disc Brake: Many bikes have a disc brake system on the front wheel. The brake caliper clamps down on a disc attached to the hub, slowing or stopping the wheel's rotation when the rider applies the brake lever.

9. Steering: The front wheel is crucial for steering the bike. By turning the handlebars, the rider can control the direction the front wheel points, which influences the bike's path.

            The composite curve is used to create a combination of two composite curves in the same plane.

12.GAS TANK:

The gas tank, also known as the fuel tank, in a bike (motorcycle) is a container that stores the fuel (usually gasoline) required for the bike's engine to operate. The size and location of the gas tank can vary depending on the bike's make and model.

The gas tank is an essential component of any motorcycle, as it provides the fuel supply necessary to power the engine and enable the bike to move. The tank is equipped with a fuel filler cap or lid on the top, which allows the rider to refuel the bike easily.

Different motorcycles may have different fuel tank designs, including various shapes, capacities, and materials. Some bikes have a traditional steel or aluminum gas tank, while others may use plastic or composite materials to reduce weight.

It's essential to maintain the gas tank properly and regularly check for any leaks or damages to ensure the bike's efficient performance and safety on the road. Additionally, it's important to follow safety guidelines while refueling to prevent accidents or spills. Always turn off the engine and let the bike cool down before refueling and avoid overfilling the tank to prevent fuel overflow.

12.CONCLUSION:

As of 2021, "American Chopper" originally aired on the Discovery Channel and then later on the TLC network. It mainly focused on the intense rivalry and sometimes tumultuous relationship between Paul Teutul Sr. and his son Paul Teutul Jr., who both ran a custom motorcycle fabrication business, Orange County Choppers.

The series went through several seasons and had some hiatuses and revivals. At one point, the show split into two different series: "American Chopper: Senior vs. Junior" and "Orange County Choppers." These shows provided different perspectives and followed the separate businesses of the father and son.

However, due to the dynamic nature of television and varying audience interests, the show's fate can change over time. It is possible that the series experienced additional revivals, spin-offs, or concluded altogether after my last update. To get the most up-to-date information, I recommend checking official sources or conducting an online search for the current status of "American Chopper" as of 2023.
