Calculated Estimation of Fatigue Life of Bearing Structures of a Mining Dump Truck Based on Complex Computer Modeling of Loading and Damage Accumulation Processes

Abstract

Methodological recommendations are presented for evaluating the fatigue life of machine load-bearing elements under the action of random processes of operational loading based on the integrated application of computer modeling technologies. The basic stages are considered for solving the problems of calculating dynamic loading, stress-strain state indicators, and evaluating the fatigue life of a mining dump truck when the machine is operating under typical operating conditions. Computational studies are implemented using a set of software tools for modeling multi-component ADAMS systems, finite element analysis ANSYS, and calculated fatigue life estimation nCODE Design Life.
