On the motion of compliantly-connected rigid bodies in contact. II. A system for analyzing designs for assembly

摘要: For pt.I see Cornell Computer Science Tech. Report (1989). A fully algorithmic, combinatorially precise approach to designing devices so that they are easy assemble and (optional) hard disassemble is presented. The analysis can be used validate good designs iterated generate improved designs. based on an algorithm for predicting the motion of flexible objects in contact. Such intended model snap-fastener-type devices, which very useful assembly design. authors describe algorithm, its implementation a system analyzing experiments run using analyze design particular devices. issues discussed include: relevance engineering, computational methods employed, algebraic techniques motions contact with rotational compliance, robustness stability geometric algorithms. Subtle mechanical difficulties arise under compliance. discuss these problems their solutions. >
