摘要
以微分学原理对平面尺寸链进行求解,简化了分析和计算过程,同时考虑了常被忽略的角度误差,提高了计算的精确性和合理性,给出了相应较为简洁的计算公式,并讨论了公差带的分布,方便了工艺人员的工艺工装设计。
In this paper, the differentiation principle is used to handle planar dimension chains. It simplifies the process of analysis, improves the accuracy and rationality of calculation because of considering the angular deviation that is usually ignored by the engi- neer. We put forward some relatively simple and efficient formula, and analyze dimension tolerance zone. The author thinks that it will further perfect the theory of dimensional chains.
