Metal Flow Rule of Multi-Way Tube Hydro Forming for Air Handling Unit
Multi-way tube on air conditioning header is considered as the research objective .Finite element simulation method is utilized to simulate and analyze the deformation process of metal. Through analyzing the distribution law of velocity on work piece neutral plane and displacement law of typical nodes, common law in deformation process for metal flow was revealed. Results suggested that: metal which is on terminal supplementary zone conspicuously flows along horizontal. Metal which is on forming zone conspicuously flows along bulge, metal which is between bulges flows little, these laws provide a reference for the choice of forming technology.
