《机械原理》中四杆机构的运动分析

Teaching Experience of "Mechanical Principle" in kinematic analysis

针对学生学习《机械原理》课程中运动分析的困惑,本文给出了低副要素的运动特点、参考点的选择、哥氏加速度存在的条件,并举例作了相应的运动分析,以提高学生对机构运动分析的分析能力和课堂教学效果。

The paper seeks to solve the confusion of students when they learn kinematic analysis in the course of ＂Mechanical Principle＂. Motion characteristics of the elements of lower-pairs, the choice of reference point, the existence terms of Coriolis acceleration, and the examples of the appropriate kinematic analysis are presented to improve the students＇ skills of kinematic analysis and effect of classroom teaching.
