装配序列生成是计算机辅助工艺规划的重要环节。在VS2005环境下，对Pro/E进行了产品装配序列生成的二次开发，求出产品的拆卸序列，进一步求反获得产品的装配序列。首先，提取零件特征信息和空间位姿信息并在自动拆卸过程中对零件进行干涉检查，建立干涉表；然后，根据零件间干涉关系选择拆卸方向，生成可行的装配序列。在此基础上，对位置特殊、沿单一拆卸方向不能拆卸的零件采用Bi-RRT(双向快速扩展随机树)算法进行路径规划，实现复杂环境中零件的拆卸，并以实例论证了方法的有效性。

Assembly sequence generation is an important segment of computer-aided process planning. The paper carries out the secondary development of Pro/ E for disassembly sequence and inverts the sequence to get the assembly sequence under the VS2005. First, the information of the feature and space pose of the parts is extracted and the interference table of parts is estab?lished after the interference checking during the process of automatic disassembly. Second, the feasible assembly sequence is gen?erated with the disassembly direction of part chosen built on the interference relationship among the parts. On that basis, the Bi-RRT (Bi-directional Rapidly Exploring Random Tree) algorithm is utilized for the path planning of the parts that can ’t be removed along a single direction because of their special positions. Then, the parts in the complex environment are disassembled successful?ly and the method using Bi-RRT algorithm is demonstrated effective according to the examples.
