摘　　要：使用常规凸轮运动规律设计的凸轮在高速运动或者从动件刚度较差的情况下,从动件容易产生余振响应。为避免这种情况出现,采用了HS的设计方法,即以理想的运动要求为目标函数来优化运动输出函数,通过凸轮机构的固有频率和凸轮运转的角频率确定谐波相数,进而求解有限项谐波叠加通式中的相的系数,从而得到运动方程。以YB49折叠转塔内的弧面分度凸轮为例进行了设计。设计结果与原FC800运动特性相比,最大加速度和最大速度值均有下降;与FOCKE701折叠转塔凸轮相比,在静止段的谐波数保持一致。因此,使用这种方法可以推广至其他高速凸轮的设计。In order to avoid result that cam follower could be vibrate on the condition bad stiffness or higher speed using routine cam motion law,the method of harmony synthesis is used. The motion output function is optimized with aim function which is ideal motion demands. Through the natural frequency of cam and angular frequency,the number of harmonic wave terms is determined. The coefficient of equation is solved. Taking the global indexing cam in the folding turret of YB49 as an esample,the design is carried out,the design result is compared with the previous cam in FC800,the value of maximum accelerated velocity and maximum velocity are declined. Comparing with the cam in the FOKCE701,the number of harmonic wave on the static state is same. So the method could be applied to the other high- speed cam.
