通过将解析法同数值法及三次插值样条函数相结合，提出了求盘形凸轮机构速度及加速度的半解析法。这种方法适合于凸轮机构的反求设计。 By combining the analytical method with the numerical method and the cubic interpolation spline function, a semi-analytical method for determining the velocity and acceleration of the disk cam mechanism is proposed. This method is suitable for reverse design of cam mechanism.
