Design And Simulation Research Of Hydraulic System Of Mining Dump Truck

The Mining dump truck is an important transport equipment to maintain the normal production of coal mine,and its working reliability decides the efficiency of coal mine production.Hydraulic system is an important part of mining dump truck.Because it controls the vehicle steering,lifting,brake and other functions,so its performance directly affects the mining dump truck using performance and security.Therefore,hydraulic system design and performance analysis of mining dump truck has been the research focus.The paper takes WCJ10E mining dump truck as the research object to design the hydraulic system and study its performance.Through the use of some mine needs and vehicle research conditions,this paper put forward a applicable to 10t mine dump truck hydraulic system,and expounded the working principle of the system in detail.The related parameter calculation and selection of hydraulic system were complated;Then the simulation models of priority valve,steering,charging valve and hydraulic cylinder,and other important components in hydraulic system are established based on AMESim software,and the simulation model of hydraulic system of the WCJ10E mining dump truck is established based on this;Respectively in the working condition of linear load and step load condition,working condition of full load lifting and light lifting conditions turn,slow tread braking mode,and points on braking condition of the hydraulic system has carried on the simulation,and the simulation results show that the presented hydraulic system of WCJ10E mining dump truck meets the design requirements,and the overall performance is good,and the scheme is feasible.The Research work of WCJ10E mining dump truck hydraulic system provides the theoretical basis for the study of optimization to improve its structure and function,and has the realistic significance to realize meeting the various specifications and functional requirements of mining vehicles for coal mine.
