摘要
在分析目前使用中的包络检测不足的基础上 ,介绍提高滚动轴承故障包络检测效果的两种方法 ,能够使包络检测的使用更具有灵活性和广泛性 ,而且还增强对滚动轴承的周期性故障冲击信号的可检测性。
On the base of analyzing shortage of envelope detection in its application, the two methods to improve envelope detection of rolling bearing faults are presented, which make envelope detection more flexibility and extensiveness and enhance detectivity of impact signals produced by cyclic failure of rolling bearing.
