摘　　要：以空调联箱多通管件为研究目标,运用有限元模拟方法对金属材料的变形过程进行模拟分析。通过分析工件壁厚的分布规律和典型节点的位移规律,由此揭示成形过程的金属流动的一般规律。结果表明:端部补料区金属沿水平方向流动较明显,成形区金属沿支管方向流动较明显,支管间的金属流动量很小,这些规律为成形工艺的选择提供了参考依据。Multi-way tube on air conditioning header is considered as the research objective.Finite element simulation method was utilized to simulate and analyze the deformation process for metal.Through analyzing the thickness distribution law of workpiece and displacement law of typical nodes,the common law in deformation process for metal flow was revealed.The results show that the metal on the zone of outer side supplementary conspicuously flows along horizontal,on the zone of forming conspicuously flows along bulge,and the metal which is between bulges flows little.The above laws supply references for choosing forming technology.
