多自由度系统微振动数态的仿真实现研究

The Multi-degrees of Freedom System of Micro Vibration MATLAB Realizes

本文以三种不同的方法即矩阵法、快速傅立叶变换法和拉普拉斯变换法分别求出振动系统的简振频率,并将拉普拉斯变换法得出的系统的微分方程的解析通过MATLAB动态仿真。

This article by three different method is the matrix technique, the fast Fourier method of transformation and the Laplace method of transformation extracts the vibrating system separately the normal frequency, and the system differential equation analytic solutionwhich obtains the Laplace method of transformation through MATLAB makes the animation simulation.
