Description
Summary:The mathematical model of cylindrical compact simulation is established by using the mathematical model of the net pressure P1 and the loss pressure P2 in AMESim environment, basing on the physical model of the powder metallurgical cylindrical blank. The simulation model of multi-step P/M parts is established by disassembling and transformation of parts, which is successfully introduced to the hydraulic system simulation. The corresponding velocity and displacement curves are obtained by running batch the three parts of B, C, A, following the principle that the speed of different height step mode is equal to the pressing rate. When the piston reaches a certain equilibrium displacement, , , and respectively range from 20 to 100, from 20 to 50, and from 50 to 2000. According to the corresponding suppression curve obtained, corresponding optimized parameters could be got to meet the requirements of the pressing speed with the AMESim optimization function.
