According to activity-on-node disassembly tree, the recursive procedure of disassembly cost is set up. 根据结点式拆卸树,构建了拆卸成本的递推算法;
It realizes the positioning and manipulation of assembly tool in virtual disassembly procedure, and gives the inspection method of wrench operator space. 对虚拟环境下工具拆卸过程进行了实现,并与其它虚拟工具交互实现方法进行了分析比较,最后研究了虚拟环境下扳手的操作空间检查方法。
