摘　　要：在材料参数以及模具结构一定的条件下,以汽车轮辐翻孔成形为研究对象,利用Dynaform板料成形软件对轮辐翻孔成形进行数值模拟。通过正交实验设计,建立了一种正交最小二乘法学习的径向基代理模型,对汽车轮辐翻孔成形减薄进行了预测。利用遗传算法对代理模型进行优化,得到了一组翻孔成形最佳工艺参数,从而验证了代理模型的合理性。Under the conditions that the material parameters and die structure were determined, taking the hole forming for car spoke as the research object, it was simulated by using Dynaform software. A RBF surrogate model based on orthogonal least square was established to predict the thinning rate in the hole forming for car spoke . At last, GA is used to optimize surrogate model to get a set of optimal parameters for hole forming.So the feasibility of the surrogate model is verified.
