| 摘 要： | 提出将近似模型引入到薄壁梁的耐撞性优化设计中,并利用序列响应面优化方法对近似模型进行优化。针对基于有限元网格模型的设计变量难于参数化的问题,开发了相应的程序将薄壁梁的材料、截面尺寸及焊点布置等参数进行参数化建模。研究结果表明:优化设计改善了薄壁梁的吸能特性,使它的质量大大减轻;基于近似模型的优化算法能较大程度地提高优化效率。

| Abstract: | It is proposed to introduce approximate model method to crashworthiness optimization design of thin wall beam,and the approximate model can be optimized by using sequential response surface method.In order to solve the parameterization design problem of finite element model,a parameterization model about material,cross section size and spotweld of thin wall beam is established by developing corresponding procedures.The results show that optimization design can not only improve the performance of absorbing energy of thin wall beam,but also reduce the weight greatly;the approximate model method can greatly improve optimization efficiency. |
