摘要：

This study proposes a piecewise high-order differential interpolation method with rapid convergence to construct an ultrasmooth high-speed cam profile. The proposed method enables a solution to be realized to manipulate the dynamic performance of a cam profile with C3 continuity during the whole working process. The reconstruction characteristics of the cam profile by the high-order differential interpolation method are compared with the most commonly used linear profile interpolation strategy. Thus, the proposed piecewise high-order differential interpolation method is validated as a feasible...
