The modal analysis of the ceramic balls rolling contact fatigue testers drive shaft

摘要：

　　The Modal Analysis of the Ceramic Ball Rolling Contact Fatigue Life Test Rig Drive Shaft With the increasing of the rolling contact fatigue life testers speed,the vibration problem is getting more and more serious.In order to optimize the dynamic performance test rig,the modal analysis of the drive shaft was carried.First the vibration mechanics model was got by simplifying the shaft and get the first order of horizontal natural frequency which is 787.4266Hz with the theoretic algorithm.Then the drive shafts modal analysis was made by using the finite element software and that is 779Hz.The relative error between the former and the latter is 1.1%.It has demonstrated the accuracy of the finite element result,and its modal analysis could be the basis of the dynamic optimization.
