面向结构教学及维修人员培训，提出了一种基于零件几何约束关系同步解除的爆炸图自动生成方法。在定义零件拆卸轴向的基础上，建立了零件邻接拆卸约束关系矩阵及约束类型矩阵，按照可同步解除几何约束的顺序对零件进行分层，并利用判断规则识别子装配体。结合应用 OBB和 FDH 两种包围盒，提出了一种“由外向内”的等速率分层牵引零件爆炸分离方法，实现了装配体组成零件爆炸图的自动生成。

To improve learning of structure design and training maintenance persons,a method for generating exploded view automatically was proposed based on synchronism release of parts geo-metric constraint relations.Part adj acency restriction relation matrix and restriction type matrix were built by defining part disassembly axial.Parts were stratifed according to the sequence of geometric constraint synchronism release,and sub-assembly was identified by defining rules.A method for parts isometric rate explosive separation form outside to inside was constructed.OBB(oriented boun-ding box)and FDH(fixed directions hulls)bounding boxes were used to realize the automatic genera-tion of assembly component parts exploded view.
