Numerical Simulation of Forming Force in Tube Multi-Point Forming

摘要

Based on the finite element theory of dynamic explicit, the technology of multi-point forming was applied to tube forming. The process of tube multi-point forming was simulated by ABAQUS software. It is used to study the behavior of forming force under different wall thicknesses and materials for manufacturing tube. It has been found that when the curvature radius is set at 1.0m, the forming force gradually becomes larger as the wall thickness of the tube increases. The careful selection of materials is beneficial to controlling forming force. Due to the technology of mass scaling, the ultimate forming force is not the maximum forming force in the process of simulation forming. However, the ultimate forming force can be used to select the multi-point forming equipment.
