摘　　要：为了进一步减小液压电机泵样机的质量,通过采用轻质材料以及合理减小结构尺寸的方法对液压电机泵壳体进行了轻量化设计,应用ANSYS软件对轻量化壳体的强度、刚度进行了分析,同时校核了钢铝连接中的螺栓强度。研究发现,液压电机泵壳体有较大的改进空间,采用6061铝合金材料及结构尺寸优化后,壳体能够满足强度、刚度的要求,且质量减小了70.1%,可见液压电机泵基于壳体的轻量化设计具有明显的效果。Aimed at the reduction of the weight of the hydraulic motor pump,a lightweight shell of the hydraulic motor pump was designed by using lightweight materials and decreasing the structure size,the strength and rigidity of the lightweight shell was tested by the software ANSYS,and the strength of the bolt connecting steel and aluminum was checked.The research showed that the design through the optimization of the structure size and the adoption of 6061 aluminum alloy satisfied the design requirements for strength and rigidity and decreased the weight of the hydraulic motor pump by 70.1%.
