Vibration Simulation Using MATLAB and ANSYS

This article demonstrates how to perform vibration simulation using MATLAB and ANSYS. First, we need to understand the fundamental principles of vibration simulation. Vibration simulation involves converting an object's vibration behavior under specific conditions into a mathematical model and simulating its vibrational characteristics through computer algorithms. Therefore, mastery of vibration mechanics and related knowledge is essential. Before conducting vibration simulations with MATLAB and ANSYS, users must familiarize themselves with both software platforms' basic operations and syntax structures. For effective vibration simulation implementation, we will cover material selection criteria, parameter configuration methods, model simplification techniques, and precision control strategies. The MATLAB implementation typically involves solving differential equations using built-in solvers like ode45, while ANSYS requires proper meshing and boundary condition setup. Finally, we provide a comprehensive program package containing script examples for both platforms to help readers better understand the simulation workflow and result interpretation. The package includes MATLAB scripts for eigenvalue analysis and ANSYS APDL commands for harmonic response studies.
