Sensitivity analysis of the influence of particle dynamic friction, rolling resistance and volume/shear work ratio on wear loss and friction force using DEM model of dry sand rubber wheel test

Popis výsledku v původním jazyce

The discrete element method (DEM) can improve wear model owing to its complexity. In this study, the laboratory results of the dry sand rubber wheel test (DSRWT) wear loss and friction force results at various loads (17 35 57 78 and 100 N) were compared with those modelled by the DEM. The sensitivity of particle parameters (dynamic friction of rubber sand, dynamic friction of sand-steel, and rolling resistance of the particle) was evaluated by variance, regression, and Pareto statistical analyses. The wheel and sample contact stress analyses confirmed that employing the progressive volume/shear work ratio parameter is required during the simulation this parameter increases/decreases the wear intensity of the tested material during the simulation.
