| 摘 要： | 轮毂轴承的预紧力会影响其工作性能和工作寿命，为了研究其作用机理，开展轮毂轴承预紧力对其固有频率影
响的研究显得尤为重要。针对某型号轿车轮毂轴承，搭建了轮毂轴承的正弦扫频激振试验系统，对不同预紧力的轮毂轴
承进行试验，得出结论：轮毂轴承的预紧力对其前3阶固有频率没有影响，第4阶固有频率随着预紧力增大逐渐增大，且
增大趋势随着预紧力增大逐渐变缓。

| Abstract: | The preloads of wheel hub bearing affects its working performance and service life. In order to study the action
mechanism. the study on the effect of wheel hub bearing preloads on the natural frequency is particularly important.
Aiming at a certain type wheel hub bearing, the wheel bearing swept sine vibration test system was built. and the
conclusion was got after testing different preload of wheel hub bearing. The conclusion shows that the first three natural
frequency of wheel hub bearing does not change while the fourth natural frequency gradually increases with the preload
increase. but the increasing trend gradually slows with the preload increase. |
