基于MATLAB遗传算法的汽车鼓式制动器多目标优化设计

摘要

针对汽车鼓式制动器,提出以制动效能因素最大、制动过程中温升最低、制动鼓体积最小为目标,进行多目标优化设计.应用惩罚函数法建立了优化目标函数,运用MATLAB遗传算法工具箱进行寻优求解,并通过实例进行验证.结果表明:该优化方法合理可行.%Aiming at the auto brake drum, with the objective of maximizing the efficacy factor of the brake, minimizing the heat of rub surface during braking and minimizing the volume of braking drum, multi-objective optimization design were made. The optimal objective function was established by using the penalty function, the optimal solution was found by using the MATLAB genetic algorithm optimization toolbox, and it was verified by an example. The result shows that this optimization method is practical and reasonable.
