APPLICATION OF SOLID ELEMENT IN IRONING SIMULATION AND OPTIMIZATION OF PROCESS PARAMETERS

Abstract

Based on viscous damping hourglass control method, a one-point integrated hexahedral finite element dynamic explicit algorithm is programmed and ironing process simulation has also been carried out. Simulation results with controlled hourglass algorithm shows that the hourglass control method is robust in this research and the setting of hourglass coefficient is analyzed. Furthermore, the reduction ratio R, friction coefficient μ between molds and blank, semi-angle α, which affect the maximum forming force, are discussed in detail. Simulation results show that the proper choice of those process parameters could obtain minimum maximum load force, thus effectively decrease moulds wear and lengthen moulds life.
