摘　　要：为了优化变速器齿轮的耐久寿命、NVH性能、重量等关键目标,考虑齿轮设计参数的复杂耦合性,提出了一种改进的随机游走算法。以某变速器齿轮强度为优化目标,考虑齿轮实际加工及变速器架构的参数约束,建立了最大化齿轮强度的优化模型,结合改进的随机游走算法进行了实例计算,并与NSGA-II遗传算法的结果进行了对比。结果表明,改进随机游走算法效率高,优化结果理想,为齿轮的优化设计提供了一种新的优化算法。In order to optimize the key objectives of transmission gears such as endurance life,NVH performance,weight,etc.,considering the complex coupling of gear design parameters,an improved random walk algorithm is proposed.Taking the strength of a certain transmission gear as the optimization goal,considering the actual machining of the gear and the parameter constraints of the transmission structure,an optimization model for maximizing the strength of the gear is established,an example calculation is carried out in combination with the improved random walk algorithm,and it is combined with the NSGA-II result.The results show that the improved random walk algorithm has high efficiency and ideal optimization results,which provides a new optimization algorithm for the optimal design of gears.
