Description: 对Gabor时频变换在模态参数辨识中的应用进行了探讨,将基于Gabor系数展开的时频滤波方法作为参数辨识的前处理手段之一,该方法对于平稳、非平稳信号都适用。根据信号在时频域内的分布特征,可以直接观测系统的频率分布情况、模态密集程度、能量聚集性、各通道响应信号所含特征量的多少等信息,从而对响应信号的特征构成进行初步判断,并通过剔除、截取等操作实现对响应信号的滤波,更有利于模态参数的辨识。

Description: 本软件主要用于结构的时域试验模态分析，包括单输入单输出，单输入多输出和多输入多输出程序设计。传统的模态分析软件大多是基于频域分析方法，需首先对采样信号进行Fourier 变换。本软件使用实测时域信号，无需Fourier变换，可以避免由于信号截断而引起泄露、出现旁瓣、分辨率低等问题对辨识精度的不利影响。此外，节省了计算机运算时间，可以对实际工况状态下的结构进行在线参数识别。-This software is mainly used for the structure of time-domain experimental modal analysis, including single-input single-output, single-input multiple-output and multiple-input multiple-output programming. Traditional modal analysis software are mostly based on frequency domain analysis, needed first sampled signal Fourier transform. The software uses the measured time-domain signal without the need for Fourier transform, avoid truncated because of the signal caused by leaks, there sidelobes and low resolution of the issue of adverse effects on the identification accuracy. In addition, the savings in computing time, to the actual condition of the structure of the state-line parameter identification.
