MATHEMATIC MODELLING AND THE DEEP DRAWING FORCE SIMULATION WITH THE WALL THICKNESS THINNING EXPERIMENT APPLICATION

Abstract

This paper presents the research based on experiment performing of the deep-drawing process with wall-thickness thinning. The corresponding measurement equipment was applied, where with the process analysis and with the applied stochastic modelling method, the physical mathematical model for the deep-drawing force is obtained, in the form: F_i = f(ψ, s₁ ,μ).

The applied modelling and simulation methods in this paper, can also be used for defining the optimal values of bigger number of the technological process parameters of deep drawing, with wall-thickness thinning, by the applied higher order mathematical model. Principally, it would relate to the reduction of the drawing force with the obtained products, according to the demanded quality along with the minimum energy consumption.
