摘　　要：通过SolidWorks对天然气压缩机气缸进行三维建模并简化,运用Simulink仿真计算得到脉动压力载荷,最后利用ANSYS Workbench进行有限元结构分析,确定气缸在动态循环过程中各种载荷作用下最大应力和变形部位,对其进行强度校核,并对相应部位提出结构改进策略。Three-dimensional model of natural gas compressor cylinder is built and simplified using SolidWorks software.Simulink software is used to simulate to get the pulsating pressure load data.Finally,ANSYS Workbench software is used to perform structural finite element analysis,which aims to determine the maximum stress and deformation position of cylinder under various loads during dynamic cycle,and to check its strength.At last,some structural improvements are carried out for the corresponding parts.
