摘　　要：为了避免轴向柱塞泵在工作过程中与工作频率一致而发生共振现象,采用大型实体建模软件Pro/E对SCY14-1B型轴向柱塞泵的壳体进行三维实体建模,然后将所建模型导入有限元分析软件ANSYS中。通过对壳体的有限元模型定义材料属性和划分网格,并对其边界条件进行约束,选用模态分析中的分块法进行求解,经过运算得到壳体的固有频率和振型,可为今后的动力学分析和振动分析提供依据。In order to avoid resonance of the axial plunger pump due to equality with working frequency during operation process, Pro/E was applied to build 3D model of the shell of SCY-14B axial pltmger pump, which was then imported into ANSYS. After definition of the shell material properties, mesh division and restriction of boundary conditions, the sub-block method of the modal analysis was applied to solve. At last, the natural frequencies and vibration shape were obtained after calculation. The study offered references for future dynamic analysis and vibration analysis.
