摘要
通过对柱塞泵内部的激振源和振动传递路径进行分析,提出了柱塞泵最终受体是壳体。对振动谐响应分析进行了介绍,并推导出振动谐响应分析的数学表达。在ANSYS中建立起柱塞泵壳体的有限元模型,并进行模态分析;根据模态分析结果,对壳体进行振动谐响应分析,确定对泵壳结构动态性能影响最大的模态频率;最终找出轴向柱塞泵正常工作状态下结构振动剧烈的区域。研究结论为轴向柱塞泵泵壳振动测试分析和结构优化提供了理论依据,为研究轴向柱塞泵减振降噪技术提供了新思路和新方法。
Through the analysis of the plunger pump vibration source and the inside transmission path,the shell is put forward as the plunger pump final receptor.Harmonic response analysis is introduced with the math expression of the harmonic response analysis derived.The finite element model of the plunger pump shell is established in ANSYS,and the modal analysis is carried on; according to modal analysis results,the shell vibration harmonic response analysis is carried on to determine the greatest impact modal frequencies on the structure of the dynamic performance of the pump shell; finally,The severe vibration area of the axial plunger pump structure is find out in the normal working state.The conclusion provides a theory basis for the axial plunger pump shell vibration test and structure optimization,new ideas and methods for studying the axial plunger pump vibration and noise reduction technology.
