Velocity Optimization on Squashing and Bending Process of Large Diameter Elbow

Abstract:

FEM simulations of squashing and bending process of large diameter elbow was applied to analyze the influence of squashing velocities, one of the key process parameters, on the deformation of the tube. In this study the squashing distance of first step is 300mm after several simulation attempts, corresponding to different squashing speeds and different bending velocities of second step. The simulation results of different velocities are compared and discussed. In the end the final velocities of the two steps are given.
