摘要
为了有效衡量拆卸过程中零部件约束方向区间的大小,提出了一种基于向位妨碍的约束状态图模型及其拆卸序列生成方法。根据零部件之间在拆卸过程中的约束类型及空间妨碍关系,提出了一种三维向位妨碍的概念及其计算方法,并构建了基于向位妨碍的约束状态图模型;在此基础上构建了相应的状态矩阵和拆卸算子矩阵,将拆卸过程转化为拆卸算子矩阵与状态矩阵的迭代运算过程,并给出了相应的拆卸规则及拆卸序列规划算法。以平口钳产品拆卸为例,进行了拆卸建模与序列规划求解,结果表明该方法有效、可行。
In order to measure the sizes of the constraint direction interval of parts effectively in the disassembly processes,a constraint graph model was constructed herein based on phase hinder and the disassembly sequence generation method.First of all,according to the space constraint in the disessembly processes and hinder with each other relations,a concept of 3D phase hinder and calculation method were put forward,and a constraint state graph model was constructed based on phase hinder.Then,in order to describe the product state and the disassembly processes,the corresponding state matrixes and disassembly operator matrixes were constructed,and the disassembly processes were transformed into iterative operation processes of the disassembly operator matrixes and the state matrixes,and the disassembly rules and disassembly sequence planning algorithm were given based on the above researches.Finally,taking a plain vice as an example,the disassembly modeling and sequence planning were solved,the results show that the method is effective and feasible.
