| 摘 要： | 利用遗传算法对代码进行优化操作的特点，研究适应轨道车辆车体结构的优化方法。以重量最轻为目标，离散的截面和板厚为设计变量，应力、指定位移和自振频率为约束，实现了集多种变量、多类约束于一身的组合优化设计，并编制了铁道车辆车体结构专用优化设计系统。

| Abstract: | In order to study the optimization method suit the railway vehicle employed the character of genetic algorithm which could proceed optimization operation to the code.Took minimum mass as objective function,discrete beam corss-section and the thickness as design variables,while stress,fixed displacement and frequency as constraints.Realized the optimum design combined with variables and constraints and compiled specific optimization system for the railway vehicle structures. |
