模拟任何振动系统的振动,都必须要先解决两个基本问题:首先就是振动激励,即引起振动的作用力问题,其次是振动系统的动态性能问题。现研究一下,球轴承在传动装置中按轴承工业常规方法进行实验时,其外圈的振动[1]。文献[2]已解决的是,球和套圈沟道具有波纹度之类工艺误差的球轴承 To simulate the vibration of any vibration system, we must first solve two basic problems: first is the vibration excitation, which is caused by the vibration force problem, followed by the dynamic performance of the vibration system. Now look at the ball bearings in the transmission device in the bearing industry by conventional methods of experiment, the outer ring vibration [1]. The literature [2] has solved the ball and ring ferrule channel with process error such as waviness
