Finite Element Analysis of Pressure Coiled Forming Process to Taper Weld Pipe
In order to reveal the deformation laws and characteristics of steel strips during the pressure coiled forming process, the stress-strain and contact force distribution of strips during the process were analyzed by the finite element ANSYS Software: the steel strips have strain along their length; strain ratios on both sides are slightly higher than that of the middle part; the equivalent force and the normal contact force in the strips are discrete distributed in the whole molding process. Compared with the corresponding experimental results, the macro experimental phenomena are basically consistent with the finite element numerical analysis rule, which provides the theoretical foundation and practical guidance for designing reasonable spiral pipe forming units.
