注塑机合模机构的多目标模糊优化设计

Multi-Objective Fuzzy Optimization Design for Clamping Mechanisms of Injection Machines

建立了以增力倍数M、行程比C、空循环次数Z为目标函数的多目标优化计算的数学模型。采用惩罚函数法调用鲍威尔法进行优化运算,并藉助于模糊相似优先此法,从非劣解中找出最接近理想解的最优解。

A mathematical model for multi-objective optimization is proposed, in which the magnification ratio of force, the stroke ratio, and the frequency of idle cyele, are employed as objective functions. Penalty function technique with calling POWELL method is performed. By use of fuzzy similar priority ratio method, the optimal solution could be found among those non-inferior solutions, which is closest to the ideal solution.
