Study On Motorizing Driving System In Mining Vehicles Based On Virtual Prototyping Technology

As one of the most important driving component in mining driving vehicles, Motorized Wheel Drive System is designed and built to provide optimal performance in mining operations, which falls into two types, AC and DC drive systems. Compared to conventional mechanical drives, motorized wheel drive systems offer lower operating costs and higher haul productivity. Electric drive systems offer many advantages when compared to mechanical drive systems by eliminating torque converters, drive shafts and transmissions.Motorized Wheel Drive Systems, combination of electric motor and speed reducer, transfers the rotational energy into torque that drives the tyres to rotate through the spline sleeve and floating sun gear of the speed reducer. Here, the permanent magnetic electric motor is applied in the system, which is apt to change the speed by frequency technology. What's more, the rotator of the electric motor will give off little heat, tremendously improving the reliability of the system.In this paper, Motorized Wheel Drive Systems are researched as follows. Firstly, the electric permanent magnetic motor is designed with the Mathcad and ANSOFT. Through the animation, optimized electromagnetism is attained. Secondly, the integrated wheel-in speed reducer is constructed applying the planet gear transferring system. Thirdly, the virtual prototyping is built by Pro/Engineer software and the ANSYS finite analysis is performed to improve the structure. Finally, some ADAMS simulations are done with the help of Proe 3D model to inspect the working conditions giving comparisons with the practical working experience.
