本发明提供一种鲁棒的振动信号特征值计算方法,对振动信号X进行短时傅里叶变换得到短时傅里叶变换频谱按列计算获得均值频谱Y,根据均值频谱Y均值mY和标准差sY设定阈值T,利用局部极大值法获得均值频谱Y中大于阈值T的局部极大值点P,找到异常突变信号,将异常突变信号中的振动信号设定为振动信号X的均值,根据有效值计算公...
RMS Locotec's hire locomotive fleet is still being moved around the country to cover operational requirements, and recent months have seen quite a few moves. RMS Locotec has lost the shunting contract at Whitemoor Yard, March, to First GBRf and at the beginning of April 08885 was moved Nor...
