摘　　要：该文讲述了计算机辅助分析驻退机湍流速度场这套软件系统。该系统由网格生成、数值计算、结果显示等几部分组成。文末对含活塞管内湍流场进行了实际计算机辅助分析。分析结果揭示了驻退机湍流场的结构和特点，表明计算机辅助分析是研究湍流场行之有效的方法。分析结果可供驻退机的设计和改进提供参考。The paper presents a kind of computer aided analysis system used to analyze turbulent flow field of recoil mechanism . The system consists of grid generation, numerical simulation and result output. Finally the computer aided analysis is really carried out in the turbulent flow field under certain condition. The simulation results display some flow characteristics in recoil mechanism, and show that numerical simulation is an effective method in investigating turbulent flow in recoil mechanism. The results are given for reference in the design of recoil mechanism.
