【Abstract】 A novel approach to find the feasible disassembly direction set is presented by applying discrete spherical algorithm to analyzing assembly constraints. This approach computes the range of all feasible local directions of removal for the component and considers the mating conditions of components in calculating disassemblability and feasible removal direction for the component. The global disassembly direction is finally determined by finding a collision free path for a component to be assembled. Experimental results show that the computation complexity of finding the disassembly direction can be reduced drastically and this method can be applied to engineering practice conveniently.更多还原
