摘　　要：提出了基于装配约束的离散化单位球面的拆卸方向计算方法首先利用离散化的单位球面计算局部拆卸方向集,通过离散点坐标的加权平均求取拆卸方向集的质心;然后通过可拆卸性判断获得可行的全局拆卸方向应用表明。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.
