| 摘 要： | 对于只给定凸轮实际廓线离散点的凸轮机构进行压力角计算,往往受限于缺少凸轮基本尺寸或无法确定从动件运动规律。本文通过对冷镦机摆动滚子从动件凸轮机构压力角求解方法的研究,详细地介绍了如何在只给定凸轮实际廓线离散点的情况下,运用三次样条插值函数求解摆动滚子从动件凸轮机构的压力角。

| Abstract: | Due to incompleted cam basic parameters or unknown motion functions of follower,it is difficulty to calculate pressure angle for cam mechanisms while only given some discrete points on actual cam profile.After the research of solution for pressure angle of the oscillating-roller-followed disk cam used in cold forging machine,the article brings forword detailed solutions under such condition above based on cubic spline interpolation function. |
