Finite Element Program for Rotor Dynamics Analysis with MATLAB Implementation

This is a finite element program developed in MATLAB specifically for rotor dynamics analysis. The implementation utilizes matrix assembly techniques and eigenvalue solvers to perform critical speed calculations and mode shape visualization. You can employ this program to conduct various analyses including rotor critical speed and mode shape identification, steady-state response under constant operating conditions, and transient response during startup/shutdown scenarios. The code architecture also supports advanced rotor dynamics evaluations such as modal analysis for natural frequency extraction, vibration characteristic assessment through frequency response functions, and unbalance response analysis using forced vibration algorithms. During operation, you can customize rotor parameters including material properties (density, modulus), geometric specifications (shaft dimensions, disk locations), and operational speed ranges through structured input modules for detailed parametric studies. The program employs numerical integration methods and finite element formulations to handle complex rotor-bearing systems. Overall, this represents a comprehensive and user-friendly rotor dynamics analysis tool that provides insights into rotor motion patterns and vibrational behavior through computational mechanics approaches.
