EDN: BQEVND
Abstract
Introduction (problem statement and relevance). A promising area for decreasing the costs for new products release is application of computer simulation in order to check new designs under operation conditions. This area allows evaluation of efficiency of new design solutions with reduction of the field tests quantity.
The purpose of the study is to develop tools for evaluation of intensity of fatigue damage accumulation of load-bearing structures of a mine dump truck body with application of computer simulation of operational loading modes.
Methodology and research methods. The paper describes the procedure developed for evaluation of intensity of fatigue damage accumulation in the load-bearing structure of a mine dump truck body with application of computer simulation methods including dynamic simulation, discrete element modeling and finite element modeling.
Scientific novelty and results. The developed procedure underwent validation studies, based on the results of which the fatigue damage accumulation rates were obtained. It has been concluded that the examined procedure allows obtaining consistent results in the field of fatigue damage of the platform load-bearing structure.
Practical significance. The developed procedure allows reduction of financial and time expenditures in development of new load-bearing structures of mine dump truck bodies by reducing pre-series prototyping of actual models and approbation of the proposed solutions.
