Rotordynamics Simulation and Nonlinear Contact Modeling in MATLAB
1. System Modeling: The Jeffcott Rotor
The Jeffcott rotor is a classic representation for analyzing rotor-bearing systems, treating the rotor as a concentrated mass on a flexible, massless shaft. The following MATLAB implementation defines the state-space equations considering viscous damping, stiffness, and unbalance forces.
