回路缺陷是机构综合中的一个基本问题。本文提出了一种识别具有4个封闭形的空间单环机构回路及其缺陷的新方法——死点法,解决了此类机构回路及其缺陷的识别问题,并实现了计算机自动识别。
Circuit defects exist in linkage synthesis. A new method for identifying circuits and their defects of a spatial single-loop linkage with four closures, namely the dead-point method, was proposed in the paper. The algorithm for automatically identifying the circuits and their defects was proposed, realizing computer identification. Finally instances were presented to explain the principles of the method.
