【摘要】：以生成正确合适的拆卸序列为目标,针对复合拆解路径问题提出改进干涉矩阵,用以表达零件之间的约束关系,以此为基础建立了干涉矩阵模型。为了避免复杂机械产品在拆卸时产生组合爆炸问题,提出了子拆卸体及其识别方法,以使得部分零件可以实现模块化拆卸。同时,引入了支撑矩阵来描述零件竖直方向的受力情况,作为拆卸中零件稳定性的判别准则。最后,文章通过机用平口钳案例验证所提出的拆卸序列生成方法的可行性。结果表明,该方法减少了生成拆卸序列的搜索工作量,有效地避免了不稳定性序列的产生。
[Abstract]:Aiming at generating correct and suitable disassembly sequence, an improved interference matrix is proposed to express the constraint relationship between parts in order to solve the complex disassembly path problem. Based on this, the interference matrix model is established.In order to avoid the problem of combined explosion in the disassembly of complex mechanical products, the sub-disassembly and its identification method are proposed, so that some parts can realize modular disassembly.At the same time, the support matrix is introduced to describe the vertical force of the parts, which is the criterion of the stability of the parts in disassembly.Finally, the paper verifies the feasibility of the method of disassembly sequence generation.The results show that this method reduces the search workload of generating disassembly sequences and effectively avoids the generation of unstable sequences.
