优化设计是将最优化理论和计算技术应用于机械设计领域,为工程设计提供优化设计的方法。MATLAB优化工具箱具有编程工作量少、语法符合工程设计习惯的特点,文章应用MATLAB软件,以减速器体积最小为目标函数对齿轮减速器进行优化设计,并给出了优化设计实例,与原设计方案相比,取得了良好的优化效果。 Optimal design is the optimization theory and computing technology used in mechanical design, engineering design to provide optimal design methods. The optimization toolbox of MATLAB has the characteristics of less programming and grammatical conformity to the engineering design habit. The paper applies MATLAB software to optimize the gear reducer with the minimum of the reducer as the objective function, and gives the optimization design examples, Compared to the program, achieved good optimization results.
