摘要: 驱动桥作为拖拉机的传动和承载部件,受力较大且使用频繁,通过对桥壳
模型的有限元分析,可以验证设计的安全性并可以通过分析结果来改进设计。首先采用Pro/E
对拖拉机驱动桥壳、转向节、半轴进行三维建模并导入Hypermesh 中进行有限元分析的前
处理工作,然后将导出的文件输入ANSYS 中进行有限元分析。最后通过桥壳的刚度试验和
疲劳试验验证了此驱动桥的安全性,并给出了改进意见。

Abstract: Drive axle sustains heavy force and is frequently used to transmit power and bear
weight of the tractor. Security of design can be verified and improved by the result of the finite
element analysis. First, hypermesh is used to proceed the preprocessing of the finite element
analysis to axle housing, steering joint, half-axle model which is designed by Pro/E, ANSYS is
used to proceed finite element analysis. By the result of the analysis and rigidity experiment,
fatigue experiment to housing, the correctness of design can be verified, and some advices are
given to increase the rigidity and fatigue lifetime for big horsepower tractor drive axle.
