摘要
本文对工作状态下的磨床动特性进行识别,通过磨削一个齿形零件,模拟输入脉冲激振,并利用倒频谱平均技术,实现有效的同态滤波,求得了磨削状态下的磨床动特性.
The dynamic behaviour of working grinder is identified in this paper. By means of grinding a geared part, simulated input of impulsing into a grinder, the effective homomorphic filtering is realized by cepstral averaging technology and the dynamic behavionr of working grinder is obtained.
