摘　　要：利用ANSYS软件建立了轴向柱塞泵的整体简化模型,并对其进行了模态分析。根据模态分析结果,对柱塞泵壳体的结构进行了优化,并分析了壳体上部分区域加厚和增设加强肋对壳体固有模态频率的影响。通过对壳体结构优化后发现,柱塞泵整体固有频率有一定的提高,这说明柱塞泵的结构刚度得到了加强,有利于柱塞泵的减振降噪。The ANSYS software was used to build the simplified axial piston pump model and its modal was analyzed.According to the results of modal analysis,a certain amount of optimization was done on the structure of the shell and the influence on the intrinsic mode frequency of the shell by regional thickening of the shell and laying some additional strengthening ribs on the shell was analysed.After the optimization of the shell structure,the intrinsic mode frequency of the piston pump has a certain increase,indicating that the structural stiffness of piston pump has been strengthened and it is conducive to reducing vibration and noise of the piston pump.
