混凝土搅拌运输车减速器的优化设计

Optimal Design of the Reducer of Concrete Mixing Truck

通过对混凝土搅拌运输车减速器设计参数的分析,发现传统的设计方案虽然满足设计要求,但往往不是最佳的。现以混凝土搅拌运输车减速器体积最小为目标函数,确定设计变量和约束条件,建立起减速器优化设计数学模型;运用MATLAB优化工具箱fmincon函数编制出目标M文件和约束M文件,运行程序求解出最优设计参数;通过计算实例可以验证,其优化结果与传统设计所得结果相比,具有明显的优化效果。

After going deep into the design parameters of concrete mixing truck reducer,it has been found that the traditional design parameters is able to match the conditions given,but not the optimal.Now taking minimum volume of concrete mixing truck reducer as the objective function,choosing design variables and constraint conditions,the optimum mathematical model is built.Target M file and constraint M file are programmed by fmincon function of the MATLAB optimal toolbox,run it and solve out the optimal design parameters.Compared with the traditional design,optimal design achieved good optimal effect through the calculating example.
