The transmission shaft–rear axle system is consisted of universal joint, hypoid gear pair, tapered roller bearing, and half shaft. In this article, as a combination of system dynamics and structure dynamics, a hybrid dynamic model of the bending–torsional–shaft vibration of the driveshaft main reducer was established to study its noise vibration harshness performance. Through dynamic frequency sweep analysis, it is found that the natural frequency of torsional vibration of the system is 53.96 Hz. Getting the natural frequency of the torsional vibration of the systems being 57 Hz by the bench tests and Adams simulations. The correctness of the nonlinear hybrid model of the driveshaft–rear axle system is proved. This research will be beneficial to the design, monitoring, and fault detection of the automobile transmission system.

基于非线性混合模型的传动轴-后轴系统耦合振动研究

传动轴-后轴系统由万向节,准双曲面齿轮副,圆锥滚子轴承和半轴组成。在本文中,结合系统动力学和结构动力学,建立了传动轴主减速器弯曲-扭转-轴振动的混合动力学模型,以研究其噪声振动的苛刻性能。通过动态扫频分析,发现系统扭转振动的固有频率为53.96 Hz。通过工作台试验和亚当斯模拟得出的系统扭转振动的固有频率为57 Hz。证明了传动轴-后轴系统非线性混合模型的正确性。这项研究将有助于汽车传动系统的设计,监测和故障检测。
