摘　　要：在UG二次开发平台上,采用模块化设计方法,研究虚拟车身坐标系装配空间确定方法等关键技术,通过定位约束映射和规则推理,给出了在三维模型空间中对检具各组合元件实施坐标变换并进行自动装配的过程,研究实例表明:计算机辅助技术的应用,能有效提高检具自动装配的效率。Method of 3-D combined checking fixture automatic assembly for auto-body part is presented. Locating constraint mapping technique and assembly rule-based reasoning are introduced. The calculating algorithm of position and pose for part model, fixture configuration and fixture elements in virtual auto-body assembly space are given. Transforming fixture element from itself coordinate system space to assembly space with homogeneous transformation matrix is realized. Automated assembly is implemented with API function based on UG. At last the aultomated assembly of combined checking fixture as a case is done and the results show that the method is feasible and high efficiency.
