摘要
以可靠性理论为基础,将齿轮的应力与强度视为服从正态分布的随机变量,通过建立以最小体积为目标,以强度、可靠性为约束的优化模型,对齿轮传动的主要结构参数进行优化设计。以某轿车减速器齿轮传动为例,建立优化模型,利用MATLAB遗传算法求解模型。与原始设计相比,经优化后齿轮分度圆体积之和减小16.4%,齿轮结构更加紧凑,实现了节省材料、降低成本的目的。
Reliability optimization design is an important design method.Based on reliability theory,combined with optimization design method,the stress and strength of the gear are regarded as random variables that follow normal distribution.By establishing the optimization model with minimum volume as the goal and constrained by strength and reliability,the design of the main structural parameters of the gear transmission is optimized.Taking the gear transmission of a car reducer as an example,an optimization model is established,and the model is solved by MATLAB genetic algorithm.Compared with the original design,the optimized gear is greatly reduced in volume and the gear structure is more compact,achieving the purpose of saving materials and reducing costs.
