摘要 综述了目前振动模态参数识别的频域方法、时域方法、时 频方法、基于小波分析与基于HHT变换的非平稳信号处理的时 频方法及基于模拟进化的方法的基本原则与具体做法 ,比较了各方法的优缺点及适用范围 。 The basic principle and technology of some methods,which including modal parameter identification in frequency and in time domain,non stationary signal process using wavelet analysis and HHT technology in time frequency domain and simulated evolution algorithm are introduced to identify modal parameter. The advantage, disadvantage and application range of each method are compared with each other.The future research direction of modal parameter identification is viewed.
