摘要
通过瞬心法对平面四杆机构进行速度分析,找到速度转折点,确定出工作行程和空回行程,研究出平面四杆机构的急回特性系数比K0用解析法精确求出急回特性系数比K,并与瞬心法做了比较,结果显示,二者的计算结果只有较小的误差。
Through analyzing the velocity by the method of instantaneous center,the velocity changing point is obviously fund,the working route and the returning route are determined and the quick-return coefficient ratio K of planar four bar mechanism is obtained.Besides the analytical method to get the ＇K＇ is finished and compared with the method of instantaneous center.Only a little difference is happened between the two results.
