采用有限元分析软件ANSYS中的APDL编程语言建立了重型牵引车驱动桥壳的参数化有限元模型，通过对桥壳本体厚度、半轴套管厚度进行优化设计，减轻了驱动桥壳的质量并增大了其强度，为轻量化设计提供了依据；分别在最大垂向力工况和制动工况下对板簧中心距进行优化设计，得到了驱动桥壳最大应力和最大变形随板簧中心距变化的曲线，确定了在最大垂向力工况下的最佳板簧中心距，在该板簧中心距范围内，驱动桥壳在制动工况下满足强度刚度要求，为驱动桥壳的设计和板簧座的布置提供了依据。

A parameterized finite element model of heavy tractor driving axle housing was established, using APDL program-ming language in the finite element analysis software ANSYS.Through optimum design on the thickness of the main body of the driving axle housing and the axle shaft sleeve, the weight of driving axle housing was reduced while its strength was increased, which provides a basis for lightweight design.Through optimum design about leaf spring center distance under the maximum verti-cal force working condition and the braking working condition, the curves of the maximum stress and deformation versus spring center distance were obtained respectively;and the optimum leaf spring center distances under the maximum vertical force condi-tion was determined.The driving axle housing met the strength and stiffness requirements in that rang of leaf spring center dis-tances.The model provides a basis for the design of the driving axle housing and the arrangement of the leaf spring seat.
