摘要
详细讨论了工频跟踪测振方法的原理 ,将机械变速过程中产生的周期振动激励信号成分有效分离 ,并以实例证明其有效性。
Variable speed machines induce vibrations or resonance at different frequencies during the speed changes.It is difficult to diagnose such problems by using standard FFT analysis.The orders tracking analysis can sort out the signal components generated by variable speed machines.In this paper,the orders tracking technique is described.The measurement principle and applications are discussed.
