摘　　要：以偏置直动尖顶推杆凸轮机构为对象,运用C#设计了一个直动推杆凸轮机构图解法教学软件。介绍了凸轮廓线图解法设计的反转法原理和基于旋转变换的软件实现原理,包括点的坐标旋转变换理论、推杆位移函数C#类库设计方法等。详细给出了凸轮机构图解法教学软件的设计步骤与运行过程。通过4个不同设计参数的应用案例说明该软件在展示凸轮廓线图解法设计原理与步骤方面的灵活性与有效性。By taking the offset straight-moving pointed push-rod cam mechanism as the object of study,a graphic teaching software for the direct-push-rod cam mechanism is designed by using C#.This paper introduces the principle of inversion method for graphic design of cam contour and the principle of software realization based on rotational transformation,including the theory of coordinate rotation transformation of points,the design method of C# class library of push-rod displacement function,etc.The design steps and operation process of the teaching software of the graphic method for cam mechanism are described in detail. The flexibility and validity of the software in displaying the design principle and steps of the cam contour graphic method are illustrated by four application cases with different design parameters.
