Dynamic Response Analysis of Compound Clearance Fault in Transmission Mechanism of Reciprocating Compressors
摘要
Abstract
The rigid-flexible coupling model dynamics simulation was carried out to study the coupling effects of multi-ple parts and various types of clearance faults caused by wear on the transmission mechanism of reciprocating compressors.Firstly,a multi-body dynamic rigid-flexible coupling model was constructed according to the first 6 modal characteristics of the transmission mechanism considering the contact force and friction as the contact constraint between the clearance of the moving pair.Then,according to the influence of different working conditions and lubrication conditions on the vibration ac-celeration of the cross head,the dynamic response of single clearance fault and compound clearance fault was analyzed.Fi-nally,the validity of the multi-body dynamic rigid-flexible coupling modeling method was verified by the measured signal of the fault test.The simulation results show that,compared with single bearing clearance fault,crosshead vibration accelera-tion decreases under the same type of bearing compound clearance fault,but increases under different types of bearing and slide compound clearance fault.In addition,with the increase of friction force and speed,the amplitude and frequency of crosshead vibration and shock will be further aggravated under compound clearance fault.关键词
