摩擦换向抽油机中摆线减速器频繁换向,关键部件摆线针轮承受正反向冲击载荷,利用可靠性理论和计算机优化方法,建立摆线轮可靠性优化的数学模型;利用MATLAB软件的概率工具箱,求解可靠度系数并寻求最优设计参数;以实例进行优化计算,验证可靠性优化方法在机械设计中的可行性与优越性,为摩擦换向抽油系统的优化设计提供理论依据。

Cycloidal reducer suffers forward and reverse shock as friction transfer pumping unit works. This paper established a mathematical model of cycloidal pinwheel using reliable theory and optimization method, and searched out the reliability and geometrical parameters of cycloid-gear by means of the probability toolbox and optimization toolbox of MATLAB. An application example shows that the method not only confirms the feasibility and superiority of optimization design in mechanical engineering but also provides the foundation for optimization design of friction transfer pumping unit.
