A method for the optimization of the drawbead geometrical parameters was built , which was based on the response surface method and genetic algorithm. 引入响应面方法和遗传算法建立基于近似模型的拉延筋几何参数反求方法。
Classical response surface method approaches the structural stochastic response using a group of general polynomials, but this method can not guarantee convergence. 摘要传统的响应面方法以一般多项式逼近结构的随机响应，但这种方式并不能保证收敛性。
