凸轮廓线接续问题探讨

在进行精密凸轮副设计时，为达到机构运动所需的行程、速度和加速等的要求，往往需要由多种类型曲线组合而成的轮廓曲线。这些曲线衔接的好坏，直接关系到整个机构的性能。我们从获得最优曲线（即给定边界条件下最短时间内达到最大速度的曲线）的条件中出发，实现了曲线接续的途径，给出了生成曲线方程的算法，并讨论了其应用实践。

Discussion of Cam Tramilion Curve

In precision cam design, several kinds of curve are needed to reach the required displacement, velocity and acceleration of motion. The transition of these different curves directly affects the performance of mechanism. In this paper, the rapidest curve transition which can reaches the maximum velocity in shortest time was discussed, the arithmetic to generate the curve equation was presented, the application of this method was also given.
