求解凸轮机构最大压力角 ,在凸轮机构的分析与设计中具有重要而实用的意义。由于凸轮机构压力角是凸轮机构位置的函数 ,传统的求法较为复杂 ,而利用高副低代法 ,可快速求解一类凸轮机构偏心轮凸轮机构最大压力角。
Evaluating maximum pressure angle (MPA) value of cam mechanism is significant and has practical applications in analyzing and designing cam mechanism.Because the pressure angle of cam mechanism is the function of the position of cam mechanism,the evaluating process of MPA is usually more complicated.The paper presents a method for evaluating rapidly MPA of one type of cam mechanisms-offset cam mechanisms by using replacement of high pair with low pair.Compared with the traditional method for solving MPA, this method is simple and easy. It not only can determine directly the position and value of MPA on the kinetic mechanism scheme,but also can adjust conveniently the geometric parameters of cam mechanisms according to the analytical formula of MPA .Therefore the method is of better value in engineering and teaching.
