摘要
以转管武器凸轮曲线槽主滚轮系统为背景,进行了高速反圆柱凸轮机构滚轮动力学分析。首先对凸轮曲线机心组系统进行加速度分解,指出了机心组最大直动加速度对系统驱动力矩的影响。以回转体转角、回转体角速度、回转体角加速度、凸轮曲线压力角为自变量,推导了主滚轮纵动加速度和主滚轮纯滚动角加速度。分别以主滚轮和机心组为研究对象,分析了主滚轮纯滚动的动力学必要条件。此研究成果将对反圆柱凸轮机构的深入研究以及改善转管武器凸轮系统传动条件具有一定的参考价值。
With the background of Gatling gun＇s cam curve slot and main roller system, dynamics analysis of high speed inverse cylinder cam mechanism was carried out. At first, the acceleration of cam curve bolt group system was decomposed, the result pointed out that the bolt group＇s maximum acceleration had some effect on driving moment of the system. Taking rotation angle of rotary body, its angle velocity, angle acceleration and the cam curve pressure angle as independent variable, acceleration and pure rolling angle acceleration of main roller system were deduced. Taking main roller and bolt group as research object respectively, by use of Newton dynamics law, the necessary dynamics condition of main roller system＇s pure rolling was analyzed. The research results can provide some reference for profound design of inverse cylinder cam and improvement of Gatling gun system driving condition.
