DETERMINATION OF THE FRICTIONAL RESISTANCE IN THE MODEL FORMING PROCESS BY THE FINITE ELEMENT METHOD

Journal Title: Tribologia - Year 2017, Vol 275, Issue 5

Abstract

This article presents the results of measurements on friction forces carried out in the model forming process (MFP). The description of this process takes into consideration the presence of plastic strain at the interface between the test specimen and tool due to the material flow. The experimental forming process was performer with a laboratory unit constructed and manufactured at the Fundamentals of Technology Faculty of the Lublin University of Technology [L. 1, 2]. This unit was used to carry out the measurements on friction force Turing model forming of shaped test specimens at a pressure of 0 to 100kN acting on a continuous basis during the research process. The results of experimental measurements of friction forces were compared to those of numerical calculations obtained with the finite element method (FEM). Experimental results of friction for ces were compared with the results obtained using the model forming process (MFP). In order to document the effects of plastic strain in the structure of shaped test specimens subjected to experimental model forming, metallographic examinations were carried out using a light microscope. Structure observations were conducted in a bright field and polarised light with a magnification of up to 2000x.
