计算机辅助传动轴设计与基于专家系统的滚触轴承选择

摘要

This paper analyzes the deformation and rotation step shaft strength through computer program. Using three dimensional modeling of gear and pulley transmission, the paper does a motion analysis of the detection on the drive shaft. Using the finite element method to calculate V shaped groove of stress concentration, and finally choose the optimal rolling contact bearing based on the knowledge of expert system.%本文用计算机程序分析旋转步进轴的强度与变形。采用三维建模齿轮、滑轮等传动元素，检测作用在传动轴上的力来进行运动分析。使用有限元公式法计算V形槽处的应力集中，最后采用基于知识的专家系统选择最优滚触轴承。
