RESEARCH ON EXCAVATION RESISTANCE OF ADAMS-EDEM COUPLING SIMULATION DRIVEN BY MEASURED DATA AND THEORETICAL MODEL (MT)
To meet the requirements of equipment performance optimization in the intelligent environment of mining machinery, a solution model of excavator resistance with wide applicability is established, which made the solution model of excavation resistance have high efficiency and accuracy. The theoretical equation of excavation force is established and solved based on d′Alembert′s principle, and its accuracy is verified by dynamic simulation. The precise soil parameters are calibrated with theoretical results, and a simulation model is constructed by coupling drive of Adams-EDEM to obtain the precise solution of excavation resistance. The accuracy of the method is verified by the measured stress. In addition, the influence of different soil parameters on simulated excavation resistance is analyzed. The results show that compared with the traditional theoretical equation, the proposed model has advantages in precision and computational efficiency. The excavation resistance output from the theoretical model is used as the standard to modify the simulated soil model. The stress output from the modified simulation model is consistent with the measured stress, which verified the accuracy of the proposed method. This method provides an important basis for the calibration of complex soil parameters and the establishment of accurate soil model.
