Numerical analysis of the ironing process under conditions of variable lateral force

Abstract

In this paper, the ironing process is analyzed using the finite element method in the case where the lateral force is variable. Ironing with variable lateral force represents a tribological model of sheet metal sliding between two contact elements that perform sheet metal thinning. The results of the numerical analysis are compared with a real experiment and based on the comparison, conclusions are drawn as to which simulation parameters provide the best accuracy of the numerical simulation. The sheet metal strips are made of two materials, DC04 steel and brass, and two lubricants are used, mineral oil and MoS2. The lateral and drawing force diagrams and sheet metal thickness are compared.
