Analysis on Force of Pressure Head during ECAP Based on Simulation
The main effect factors about force of pressure head (FPH) are investigated by numerical simulation for the process of equal-channel angular pressing (ECAP). The influence of extrusion mould design parameters which including corner angler ( ) and corner radius (R), friction condition between mould’s inner wall and multi specimen in the mould, different last location of pressure head and extrusion specimen etc on force of pressure head, are analyzed and discussed by numerical simulation.
