Abstract:
It is proposed to introduce approximate model method to crashworthiness optimization design of thinwall 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,crosssection size and spotweld of thinwall beam is established by developing corresponding procedures.The results show that optimization design can not only improve the performance of absorbing energy of thinwall beam,but also reduce the weight greatly;the approximate model method can greatly improve optimization efficiency.
