对平面回转运动的分析是研究转轴空间回转运动的基础.本文将根据对平面回转运动的几何学分析来研究回转运动的瞬时回转中心(简称瞬心)与回转运动误差之间的关系.讨论瞬心线与轮转曲线的关系及其物理意义.并通过计算机仿真来分析和讨论有关偏心、一次谐波、敏感方向等问题.
The analysis of plane rotary motion is the basis for the study of the rotary motion of the shaft.In this paper, we will study the relationship between the instantaneous rotation center (instantaneous center) and the rotary motion error of rotary motion based on the geometrical analysis of plane rotary motion. The relationship between heart line and rotation curve and its physical meaning.And the problems of eccentricity, first harmonic and sensitive direction are analyzed and discussed by computer simulation.
