Assembly & Simulation
Fusion 360 offers robust capabilities for both assembly modeling and simulation, allowing users to design and analyze complex mechanical systems. Here's an overview of assembly and simulation in Fusion 360:
Assembly Modeling:
Fusion 360 provides tools for creating assemblies of multiple components, allowing you to simulate the interaction and movement between parts. Components can be imported from external files or created within Fusion 360 using various modeling tools. The \Assemble" tool allows you to position and constrain components relative to each other, defining relationships such as mates, joints, and contacts. Fusion 360 offers a variety of assembly constraints including mate, flush, tangent, align, and more, enabling precise control over component positioning and motion. Motion Studies:
Fusion 360 enables users to perform motion studies to simulate the movement of assemblies and analyze their behavior. Motion studies can be used to evaluate mechanisms, test different design iterations, and verify clearance and interference between components. Users can define motion constraints, such as motors, gravity, springs, and contact conditions, to accurately represent real-world behavior. Motion studies can be animated and analyzed to understand how the assembly behaves under different operating conditions.

Computational Fluid Dynamics
Computational Fluid Dynamics (CFD) is a computer-aided engineering tool that uses numerical methods to simulate and analyze fluid flow. It solves complex equations governing fluid motion (like the Navier-Stokes equations) to predict properties like pressure,
temperature and velocity. CFD is used in many fields like aerospace,
automotive and energy to design better products (like airplanes and cars) and improve processes (like combustion). While powerful,
CFD can be computationally expensive and complex,
especially for simulating turbulent flows. Overall,
CFD is a valuable tool for engineers working with fluids.
task 3
Generative Design: Generative Design
Generative Design in Fusion 360 is a cloud-based tool that helps engineers design complex parts. It works by exploring many possible designs based on user-specified goals (like minimize weight) and limitations (like material properties). Users define things like loads, supports, and materials, and then the software generates many possible designs. Users can then pick the best design and refine it further, or export it for manufacturing using Fusion 360's built-in tools. This speeds up the design process and helps create innovative solutions.

Sourcing & Materials Selection
Creating an electric bicycle requires careful consideration of various components to ensure that the final product meets the specified parameters. Here's a detailed list of inventory required for building an electric bicycle with the given parameters:
Frame:
Lightweight and durable frame capable of supporting a maximum weight of 90kg. Material: Aluminum or carbon fiber for a good balance of strength and weight.
Electric Motor:
Brushless DC (BLDC) hub motor for the rear wheel. Power rating: Sufficient to achieve a maximum speed of 40kmph.
Battery:
Lithium-ion battery with high energy density. Voltage: Suitable for the motor and controller. Capacity: Sufficient for a maximum range of 50km per charge. Mounting: Integrated into the frame for aesthetics and stability.
Controller:
Electronic controller to manage power flow from the battery to the motor. Compatible with the motor and battery specifications.
Throttle:
Twist grip or thumb throttle to control the speed of the electric motor. Integrated with the handlebars for easy access.
Brakes:
Hydraulic or mechanical disc brakes for effective stopping power. Ensure the brakes can handle the additional speed and weight of the electric system.
Wheels and Tires:
Sturdy wheels capable of handling the increased weight and speed. Puncture-resistant tires for improved reliability.
Suspension System:
Front suspension fork to enhance rider comfort. Consider a rear suspension system for additional comfort, especially if riding on uneven terrain.
Transmission:
Single-speed or multi-speed gear system depending on the terrain. If multi-speed, choose a derailleur or internally geared hub based on preferences and maintenance considerations.
Pedals:
Standard bicycle pedals for manual pedaling when desired. Pedal-assist sensor (optional) for a hybrid electric and manual riding experience.
Lights:
Front and rear LED lights for visibility and safety. Integrated wiring into the frame for a clean look.
Display/Control Panel:
LCD display showing speed, battery level, and other relevant information. Handlebar-mounted control panel for easy access.
Frame Mounting Accessories:
Mounting points for the battery, controller, and other components. Cable management system for a neat and organized appearance.
Charger:
Battery charger compatible with the voltage and capacity of the lithium-ion battery.
Miscellaneous:
Kickstand for stability when parked. Reflectors and other safety features to comply with regulations. Ensure that the components are sourced from reputable manufacturers and are compatible with each other. Additionally, consider the local regulations regarding electric bicycles to ensure compliance. Regular maintenance and safety checks are essential to keep the electric bicycle in optimal condition
Task 5
Create A Voltage Multiplier!!
A voltage multiplier is an electronic circuit designed to generate a higher voltage from a lower input voltage. It typically consists of a series of capacitors and diodes arranged in a ladder-like configuration. When alternating current (AC) or pulsating direct current (DC) is applied as the input, the voltage multiplier circuit produces an output voltage that is a multiple of the input voltage.
Task 6
Create a circuit that provides short-circuit protection.

Short circuit prevention using a relay involves employing a relay, current sensor, and control circuit to detect and respond to short circuits in a circuit. The current sensor monitors current flow, and if it exceeds a predetermined threshold indicating a short circuit, the control circuit triggers the relay to interrupt the current flow, preventing damage to the circuit components. This approach provides a simple and effective way to safeguard against short circuits in electrical systems."
