|Title:||A Numerical Investigation on Magnetic Pulse Cladding of Bi-Metal Tubes|
|Abstract:||Bimetal tubes are widely applicable in refrigerating industry, liquid conduit systems and other similar installations. Magnetic pulse cladding (MPC), based on a sequential joining/welding of lapping portions of long tubes, is a novel approach to fabricate bimetal tubes. This work presents an efficient numerical simulation of the MPC process to analyze the dynamic deformation and its effect on cladding result from a numerical view. A 2D axisymmetric model was established and a multi-steps cladding by forming was simulated based on the models similar to an actual MPC process. Between two subsequent steps, the stresses and strains were transferred from previous step to next one. The model predictions and experimental results were compared by the contour of the clad tube and showed an acceptable agreement. The advantages of a new field shaper with tile angle α1 of 3° and angle α2 of 13° were presented, and the magnitude of the magnetic pressure, the stress-strain field and velocity of collision were investigated. The numerical simulation benefits the process knowledge and assists the design of the field shaper.|
