针对现有装配关系模型在结构完备性、获取复杂性等方面的不足,研究了装配关系模型重构和装配关系信息自动获取方法.提出接触-连接矩阵,用以集成功能件和连接件间的接触关系和各类连接关系,并研究了利用静态问隙分析和工程语义解析来获取接触-连接矩阵的方法.提出扩展于涉矩阵,以解决现有干涉矩阵无法有效处理倾斜方向装配的问题,支持装配方向的优化求解,并研究了基于包围盒扫描和步进检测生成扩展干涉矩阵的方法.以UG为平台,开发了原型系统,并以具有非标准轴向装配的夹具为例,验证了该方法的有效性.

Aiming at the deficiency in structure representation and information acquisition of existing assembly relationship models, methods for assembly relationship models reconstruction and automatic acquisition of assembly relationship information were studied.Contact-Connection Matrix (CCM) was proposed to express contact relationships and various types of connection relationships among functional parts and connectors.Static clearance analysis and engineering semantics analysis were adopted to set up CCM.Then,Extended Interference Matrix (EIM) was put forward to effectively solve assembly problems in tilt directions,which other existing methods were incapable of,and assembly direction resolution could also be optimized based on it.Approaches based on sweeping-boundingbox and stepping-detection to establish EIM were discussed.Finally,prototype system was developed based on UG platform,and the effectiveness of this method was verified by the fixture with tilt assembly directions.
