摘要：

为了获得更好的并列双支管成形高度，基于内高压成形工艺的特点，对并列双支管成形过程中的加载路径参数进行优化。通过Design Expert软件进行试验设计，采用ABAQUS有限元软件对并列双支管内高压成形过程进行了模拟研究。以支管高度及减薄率为目标函数，借助Design Expert方差分析分别验证了支管高度（BH）和减薄率（TR）函数模型的可信度，通过期望值方法对多目标进行优化分析，形成一条并列双支管内高压成形优化加载路径。采用该优化加载路径进行试验验证，通过ABAQUS、试验、RSM分别对比了支管高度、减薄率，试验与RSM支管高度误差在0.9 mm以内，试验减薄率比RSM预测值高3.5%。

To obtain a better forming height of parallel doublebranch, the loading path parameters in the parallel doublebranch forming process were optimized based on the characteristics of the internal high pressure forming process. The experimental design was carried out by using Design Expert, and the simulation study of internal high pressure forming process for parallel doublebranch was made by using finite element software of ABAQUS. Taking the branch height（BH）and thinning ratio（TR） as objective functions, the credibility of them was verified based on the variance analysis in Design Expert. By optimizing and analyzing multiple objects through expected value method, an optimized loading path of internal high pressure forming for parallel double branch was formed. And by using the optimized loading path to verify the test, and comparing the branch height and thinning ratio in ABAQUS, experiments and RSM respectively, it is found that the height error of branch is within 0.9 mm and the experimental thinning ratio is 3.5% higher than the expect value in RSM.
