Numerical Simulation of Pressure Influence on Workpiece Properties during Thixoforging
Numerical simulation of pressure influence on the relative densities of both solid and hollow cylindrical workpieces during Thixoforging was carried out by using ANSYS software. The results showed that there was a big difference in relative density between different points within the workpiece during Thixoforging with the use of a single punch. Therefore, partial feeding with the help of assembly punches was proposed to improve workpiece density uniformity and properties, and the effectiveness of this approach was well-demonstrated by numerical simulation.
