摘要: 针对机械系统优化中因设计变量耦合关联导致的优化结果可靠性问题,提出了基于加权满意度的耦合关联机械系统多目标协同优化方法。建立机械系统设计变量耦合关联模型,采用最大-最小满意度函数法,并考虑各子目标的相对权重,建立基于权重加权和的多目标协同优化评价函数,将多目标优化问题转变为单目标优化问题。以掩护式液压支架四连杆机构-结构多目标协同优化为对象的应用表明,提出的方法简化了耦合关联机械系统多目标优化求解的复杂度,而且提高了优化结果的可靠性。

关键词: 多目标优化, 耦合关联, 满意度, 掩护式液压支架

Abstract: Aiming at the mechanical system optimization result reliability problems caused by design variables coupling relation, based on weighted degree of satisfaction and coupling relation, a mechanical system multi-objective collaborative optimization method was proposed. At first, the coupling model for design variables of mechanical systems was established. And then, using maximum-minimum satisfaction function, considering sub-objective weighting factors, a weighted multi-objective collaborative optimization evaluation function was build. At last, the applications of mechanism-structure multi-objective collaborative optimization design of shield type hydraulic support four-bar prove the method may simplify optimization solution processes and improve the optimization result reliability.

Key words: multi-objective optimization, coupling relation, satisfaction degree, shield type hydraulic support
