Finite Element Simulation
Analysis of ironing operation under dry and lubricated conditions
Tribological system can be explained by evaluating the forming forces and distributions of the contact pressure and temperature in the active contact sliding region between the die and the workpiece surfaces. By performing a numerical simulation combining mechanical and thermal analysis, two important influencing factors can be determined – the friction and the heat generated at the die–workpiece contact surfaces under dry and lubricated conditions. Here, we show some examples within our capabilities. A two-dimensional model of the strip-reduction test of stainless steel was analyzed using implicit time integration. To reduce the computation time, only half of the ironing process was modeled; i.e., the plane strain with quadrilateral elements was meshed for the die and workpiece. A fine, uniform mesh was applied in the contact region between the workpiece and the die surface.
