摘　　要：以并排多通管内高压成形工艺为研究对象,在支管总间距一定的条件下,相邻支管间距由外到里成等差数列,对几种典型支管排列方式下并排多通管内高压成形工艺进行模拟分析。结果表明:在相同加载路径条件下,相邻支管间距由外到里逐渐增加时支管平均高度高于支管等间距排列和支管间距由外到里逐渐减小的排列方式,此时支管等间距排列时支管高度分布最均匀。加载路径修正后,相邻支管间距由外到里逐渐增加的支管排列方式得到的支管平均高度明显高于其他排列方式,且增加幅度越大,支管平均高度越高,各支管高度分布越均匀。不同支管排列方式最终得到的并排多通管壁厚分布规律基本相同。Parallel arrangement multi-way tube hydrofornaing technology was considered as research objective. Under the condition of total distance between branches is invariant, the distance between adjoining branches is arithmetic sequence from outside to inside. Parallel arrangement multi-way tube hydroforming technology of different branches rank ways are simulated and analysed. The results show that under the condition of same loading path ,average branches height for distance between adjoining branches increase from outside to inside is higher than average branches height for branches rank evenly spaced and rank way for distance between adjoining branches decrease from outside to inside, at this time, the distribution of average branches height is most homogeneous. After loading update, average branches height for distance between adjoining branches increase from outside to inside is obviously higher than other rank ways,and when distance between adjoining branches increase more from outside to inside, average branches height is higher and distribution of average branches height is more homogeneous. The rule of parallel arrangement multi-way tube with last thickness distribution are probable the same for different rank way of branches.
