Roller Coaster Simulation
Abstract
This project simulates the motion of a rollercoaster cart propelled by a Permanent Magnet Linear Synchronous Motor (PMLSM) across a complex track profile. The simulation incorporates realistic physics including gravitational forces, friction, and air resistance to analyze whether the motor's 4-second thrust is sufficient to complete the course. Developed in MATLAB/Simulink, this model serves as a valuable tool for roller coaster design and safety analysis.
