COMPUTATIONAL SIMULATION OF CUMULATIVE FATIGUE DAMAGE PREDICTION OF THE LORRY FRAMES

Abstract

The basic aim of this paper will be to present FEM application in the TATRA 815 lorry frame construction fatigue life estimation. Construction critical nodes from the fatigue damage point of view have been found and analyzed. Analysis of the particular traffic states influence on the fatigue damage cumulation is going to be presented too.
