摘要

为了解决载重车辆驱动桥壳设计安全系数较大、制造成本高等问题,建立载重车辆驱动桥壳参数化有限元模型,通过将驱动桥壳系统关键结构参数设置为分析变量,运用静、动力学及疲劳寿命方法研究结构参数变量对载重车辆驱动桥壳力学特性的影响,为载重车辆驱动桥壳的设计和参数的选择提供了参考依据。研究结果表明,驱动桥壳本体总长与桥壳左右两侧挡板距离增加,将会提高驱动桥壳最大应力值与变形值;桥壳本体总长与桥壳左右两侧挡板距离两参数对驱动桥壳固有频率影响有限,而板簧座中心线距离对驱动桥壳固有频率影响明显。

Abstract

To solve the problems of high design margin and high manufacturing cost of heavy vehicle drive axle housing,the parametric finite element model of heavy vehicle drive axle housing is established,through the drive axle housing of key structure parameters are set for the analysis variables,the influence of the structure parameter variables on the heavy vehicle drive axle housing mechanics characteristic is researched by using static,dynamic and fatigue life method,the reference for the design and choice parameters for the heavy vehicle drive axle housing is provided.The results show that the axle housing body length and the axle housing both sides of the baffle plate distance increase,the maximum stress value and deformation value of drive axle housing will increase;the axle housing body length and the axle housing around both sides of baffle plate distance of two parameters have less influences on natural frequency of driving axle housing,and the distance of the center line of the spring seat has great influences on natural frequency of drive axle housing.
