Detailed Documentation

The following MATLAB code simulates the motion of mechanical four-bar linkage mechanisms. This implementation features comprehensive motion simulation capabilities and includes functions for generating analysis plots that track variable changes over time. The simulation utilizes kinematic equations and matrix operations to calculate link positions and velocities at each time step. Key algorithmic components include: - Forward kinematics calculations using trigonometric relationships - Position analysis through vector loop equations - Velocity and acceleration computations via differentiation methods - Animation functions using MATLAB's plotting capabilities with real-time updates The simulation results provide insights into the motion principles of four-bar linkages, while the variable analysis functionality enables systematic parameter studies for mechanical system optimization. Users can modify parameters such as link lengths, joint positions, and input angular velocities directly in the code to simulate various motion scenarios and mechanical configurations. The code structure allows easy extension for different linkage types and supports both open-chain and closed-chain mechanisms. This implementation serves as a valuable tool for engineering design projects and simulation research, offering both educational value for understanding mechanism dynamics and practical utility for mechanical system optimization.
