    摘 要:对断路器合闸过程中凸轮滚子进行了受力分析,得出了凸轮压力角α及超程与凸轮转角β之间的函数关系式,进而将滚子所受的力表示成β 的函数。用MATLAB软件绘制出力与β 的函数关系图,并用ADAMS对符合实际情况的凸轮模型进行了动力学仿真,理论计算和仿真分析所得结果基本一致。该分析结果可用于凸轮受力分析及其相关零部件的设计、强度校核,同时也为断路器机构的弹簧力输出特性与断路器的负载特性之间的匹配提供理论依据。

    Abstract: Force analysis was made to the cam and roller in the process of circuit breaker closing to obtain the cam pressure angle α and the function relationship between the overrun and the cam angle β, so as to make the force received from the roller express as a function of cam angle β. MATLAB was used to draw the function relationship diagram between the force and cam angle β, and ADAMS was used to carry out the dynamics simulation for the cam model that conformed to the actual situation. The theoretical calculation was close to the result of the simulated analysis. This result could be used in analyzing the cam bearing, the design of related parts and the intensity check, which provides a theoretical basis for matching the spring force output characteristics of circuit breaker mechanism and the load characteristics of circuit breaker.
    Key words: breaker; cam; function relationship; dynamics simulation
