Simulation of a 3D Mechanical/Aerospace System

Journal paper: Dynamics of coin tossing is predictable

  • Simulated the dynamic behavior of a tossed coin based on the initial conditions in MATLAB using Euler angle sequences
  • Initially, the model was developed for the coin before impact. 
  • Then, based on Newton’s hypothesis of coefficient of restitution, Conservation of linear and angular momentum, and the nature of contact between the coin and the ground surface, the coin’s impact was modeled and the magnitude of the states for the rebound phase of coin motion was calculated. 
  • The simulation was carried out till the coin came to rest. 
  • This project gave me experience in building a dynamic model of a system from the ground up and simulating it using MATLAB programming instead of going for an already available Multibody Dynamics simulation software.
