The Influence of Process Force on the Wall Thickness

Abstract:

Multi-way tubes on air conditioning condenser are considered as research objective. The ordinal hydro-forming method and finite element simulation method are utilized to analyze the influence of process force on wall thickness such as internal pressure, axial force ,balance force and their matching relationship. The uniform experimental design method and regression method are utilized to solve the prediction model of wall thickness. The results show that the slope of straight line loading path has a significant effect on branch height, the greater the slope is, and the higher the height is. What’s more, the fold line loading path can effectively improve the branch height while the shock loading path can effectively improve the wall thickness‘s uniformity.
