摘要: 提出三个多项式凸轮曲线族。使用者可根据不同的用途,用优化方法求得待定系数值,从满足边界条件的曲线族中挑选出一条综合性能最优的凸轮曲线。还提供了待定系数与所选凸轮曲线的诸特性值之间关系的图表。Abstract: This paper proposes three groups of polynomial cam curves,By evaluating theundetermined coefficient with optimization method in the light of specific usage,users maychoose an optimum curve from a set of the cam curves which must satisfy the boundary conditions.The paper provides figures which describe the rela tionship between the undetermindcoefficients and the characteristic values of the chosen cam curves.
