Simulation of Swaging Process

Various tube and bar end forming technologies are widely used in the manufacturing industry. We present, in the above animation, an analysis of one such technology known as swaging.

Engineers designing swaging operations need to analyze and test several technological parameters before production proceeds. The ADINA System allows real forming processes to be evaluated in a short time, as in this example. The simulation was performed with ADINA's 27 node u/p element, with excellent characteristics that allow the use of only one layer of elements through the tube thickness. The rigid target algorithm, specially adapted to metal forming process simulations, was used with an implicit time integration scheme, thereby enabling the application of the same physical parameters in the simulations without the need for mass or tool velocity scaling. Consequently, the simulation results give the engineers greater confidence that the choice of process parameters will yield a product that conforms closely to specifications.
