摘要
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做成动画模拟。
The frequency of harmonic vibration of the vibration system was figured out by matrix technique,fast Fourier-transform and Laplace transform method separately.The resdution of the differential equation of system gained by Laplace.transform method was struck out animation simulation by Matlab.
