摘　　要：针对轻武器行业"人工修锉"问题和企业数字化设计与制造需求,利用VSA软件进行了某手枪击发机构三维装配公差分析,得到了与实际装配情况一致的结果,说明基于三维模型的计算机辅助公差设计技术适用于轻武器设计制造公差控制,在轻武器数字化设计制造过程中可以为实际设计、制造提供支持,减少工程更改。在此基础上提出了CAT在数字化协同设计和制造环境下系统信息化集成框架、应用模式、数据模型和数据交互方式等,为后续系统的开发、集成与应用提供了参考。To solve the repair problem of small arms and digital design and manufacturing requirements of enterprise,3D assembly tolerance for firing mechanism of a pistol was analysised based on VSA,the results obtained are consistent with the actual situation,indicating that CAT based on 3D model is suitable for tolerance analysis on the design and manufacturing, and can provide support and reduce the changes in the process of digital design and manufacturing for small arms.Based on this, integration framework, application model, data model and data exchange method of CAT in the digital design and manufacturing systems are proposed,it offers reference for exploitation ,integration and application of the subsequent system.
