Numerical Simulation of Prism Cavity Split Type Ultrahigh Pressure Die Based on Steel Wire Winding
We propose a novel structure of ultrahigh-pressure die which consists of a split com-pression cylinder,a support ring,and steel wire winding,and the effects of the circular and prismatic cavities on the stress level and stress distribution of the mold are investigated.First,it is determined theoretically what the maximum cavity pressure and the necessary number of winding layers would be.Then,the finite element method is used to calculate and compare the stresses from various angles,such as the shear stresses of the press cylinder and the support ring,and the axial stresses of the steel wire layer.The numerical simulation results show that compared with the circular cavity steel wire winding split mold,the stress and stress distribution of the prismatic cavity mold is more reasonable,and the pressure inside the cylinder is more capable of transferring to the outside,with high material utilization.The findings indicate that the prismatic cavity cylinder can withstand higher internal pressure.
