The invention provides a novel wave generator cam design method. The method comprises the main steps of finite element model establishment, boundary condition introduction, analysis and calculation, fitting and the like. The outer edge curve of the cam designed by using the method conforms to a curve formula calculated by using the method instead of a standard ellipse, and the harmonic reducer ofthe wave generator cam designed by using the method can effectively reduce the problems of tooth surface abrasion, wave generator downward pressing, jumping, abnormal sound and the like. 本发明提供了一种新的波发生器凸轮的设计方法，包含建立有限元模型、导入边界条件、分析计算、拟合等几个主要步骤，使用这种方法设计的凸轮外缘曲线符合通过这种方法计算出的曲线公式而不是标准椭圆，应用这种方法设计出的波发生器凸轮的谐波减速器，可以有效减少齿面磨损、波发生器下压以及窜动、异响等问题。
