基于LabVIEW的倒频谱在齿轮和滚动轴承故障诊断中的应用

THE APPLICATION OF CEPSTRUM IN FAULT DIAGNOSIS FOR GEAR AND ROLLING BEARING BASED ON LabVIEW

介绍了利用LabVIEW平台检测齿轮和轴承故障信号,叙述了在LabVIEW的环境内,使用MATLAB对齿轮振动信号进行倒频谱分析,提取齿轮故障特征信息,实现齿轮故障诊断.并通过实验验证此方法的可行性.

LabVIEW flat is introduced to detect the fault signal of gear and rolling bearing. In the condition of LabVIEW, it makes use of MATLIB for Cepstmm analysis of gear oscillation＇ s signal. It gives characteristic information of gear fault. This methd enables to realize gear fault diagnosis, and feasibility of the method is demonstrated with an example.
