用导出的矢量参数形式组合的五次 Hermite插值曲线 ,在二阶连续条件下应用于凸轮运动曲线的设计。其特点是在满足了内点的边界条件的同时 ,还有富余的自由度可用于对曲线的形状进行调整。这一特点使得以往在插值后靠“有限差分法”等方法来改善凸轮曲线的特性转变为对这些自由度的调整 ,这种调整对设计条件没有影响 The fifth Hermite interpolation curve combined with the derived vector parameters is applied to the design of cam motion curve under second order continuous condition. It is characterized by the fact that while satisfying the boundary conditions of the interior point, there is also a margin of freedom that can be used to adjust the shape of the curve. This feature makes the past, after interpolation by “finite difference method” and other methods to improve the characteristics of the cam curve into the adjustment of these degrees of freedom, this adjustment has no effect on the design conditions
