摘　　要：根据车身概念设计阶段中关键截面外形受到车身造型和内部空间的约束,提出了一种具有满足截面性能指标的截面加强板形状优化生成方法。该方法采用节点法的思想,将加强板分成若干个节点,通过节点控制加强板的形状,基于modeFRONTIER软件采用多目标遗传算法(MOGA-Ⅱ)进行求解。针对某车型A柱梁截面的加强板,通过建立多目标优化设计模型进行了求解,验证了该方法的有效性。In this article,according to the requirement of the automotive body’s shape and internal space constraints on the shape of key body sections in the body’s concept-design stage,a method is proposed to optimize shape generation of the section-reinforcement plate with desirable index of section performance.The node idea is adopted,and the reinforcement plate is divided into several nodes,in order to control the reinforcement plate’s shape with the help of the nodes,and solve it by means of the multi-objective genetic algorithm(MOGA-Ⅱ)in the modeFRONTIER software.This method is validated by setting up a model of multi-objective optimization design for the reinforcement plate of an automotive body’s A-pillar beam section.
