经验模态分析（EMD）的MATLAB计算算法，经验模态分析是机械振动分析领域的重要方法-Empirical mode decomposition (EMD) of the MATLAB computing method, empirical mode analysis is an important field of mechanical vibration analysis method

模态分析，用FFT对输入的激励信号提取振动的频率-Modal analysis using FFT excitation signal input to extract vibration frequency

冲击理论指的是计算结构响应的风动荡。这里,结构是一个吊桥,使用连续梁的理论建模。介绍模态耦合模型，尽可能的简单计算横向,纵向和扭转响应。结构的方法是使用。是专为那些已经拥有一些知识领域的随机振动分析和对结构风荷载。-The buffeting theory [1,2] refers to the computation of the response of a structure to wind turbulence. Here, the structure is a suspension br

可以用来分析简支梁振动模态以及频率，简单高效，可以得到简支梁的动力特性(It can be used to analyze the vibration modes and frequencies of simply supported beams. It is simple and efficient, and the dynamic characteristics of simply supported beams can be obtained.)
