摘要
在空气压缩机的振动实验中,为得到不受噪声影响的缸体振动响应,将浮动阈值法和李普西兹指数法相结合,应用正交小波变换将噪声从振动信号中分离出去,得到了良好的降噪效果。
During air compressor tests, perpendicular wavelet theory is applied with the combination of floating threshold and lipschitza exponential method,in order to get vibration response of cylinder without noise and good results are given.
