驱动桥壳是装载机的主要承载构件,承受着多个方向的载荷,应具有足够的强度和刚度。传统铸造桥壳存在制造周期长、工艺复杂等不足之处,为简化工艺、降低成本,研制开发了一种新型冲压焊接结构驱动桥壳。利用有限元分析软件ANSYS建立了ZL50型装载机冲压焊接结构驱动桥壳的有限元分析模型,对桥壳进行了3种典型工况的分析计算,获得了该结构桥壳在各工况下的变形和应力分布,结果表明桥壳能满足各工况工作要求,为下一步的结构优化设计提供了理论依据。
Drive axle housing is the main load-bearing components of the loader, to withstand the load in multiple directions, should have sufficient strength and stiffness. The traditional cast axle housing has the disadvantages of long manufacturing cycle and complex technology. In order to simplify the process and reduce the cost, a new type of drive axle housing with stamping welded structure has been developed. The finite element analysis model of the drive axle housing of the ZL50 typed loader stamping welded structure was established by the finite element analysis software ANSYS. Three kinds of typical operating conditions of the axle housing were analyzed and calculated, and the mechanical properties of the axle housing under various operating conditions Deformation and stress distribution. The results show that the axle housing can meet the requirements of various working conditions and provide the theoretical basis for the next structural optimization design.
