摘　　要：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 。The 5th order Hermite insertion value curveof the combination of derived vector parameters is used in designing cam motion curve in the case of the second order continuation, whose characteristics is that apart from satisfying the boundary conditions of inner points, there is still rich freedom which can be used to adjust curve configation. This characteristics makes it possible that the cam curvature property improved by depending on the finite difference method after the value insertion can be converted into the adjustment of this freedom. This kind of adjustment will have no effect upon design conditions.
