- Abstract
In this paper, aiming at the main problems existing in the carriage of the mining dump truck in service, the longitudinal section curve configuration of the carriage is studied in combination with three factors: material performance, rated volume of the carriage and smoothness of unloading. The discrete element method is used to simulate the movement of the material and the interaction between the material and the bottom plate at the rear of the carriage. At the same time, the unloading experiment is carried out under the condition of full load. The experimental analysis is consistent with the theoretical and numerical simulation results. The results show that the longitudinal section of the carriage is the best when it is "arc + polynomial curve + straight line + arc".
