索道设备共振现象分析及消除措施

Analysis and elimination measures of resonance phenomenon of cableway equipment

共振对机械设备平稳运行有很大影响,索道出现共振将严重影响其安全运行。通过分析共振现象的产生机理,总结出共振产生的原因。共振状态中包含机械系统的固有频率、最大响应及振型等信息。通过分析几个共振案例,介绍共振现象成因的排查方法以及相应的消除措施。

Resonance can strongly affect the smooth operation of mechanical equipment.The occurrence of resonance in cableway will have great influence the safe operation.The paper summarizes causes of resonance by analyzing the mechanism of resonance phenomenon.The resonance state includes the natural frequency,maximum response and mode shape of the mechanical system.Through the analysis of several resonance cases,this paper introduces the methods of checking the causes of resonance phenomena and the corresponding elimination measures.
