The action of some uncertainty factors on system characteristics is difficult to be described accurately by mathematical model, and the validity of simulation model has yet to be verified when hydraulic steering technology of articulated dump truck is studied theoretically. The main parameters include oil pressure and flow rate of hydraulic steering system were studied by vehicle test method in this...
The steering smoothness of articulated dump truck is impacted directly by the flow, pressure and power of the hydraulic system. The main parameters of hydraulic steering system were studied by mathematical analysis and calculation in this paper. The results show that articulated dump truck constant power hydraulic steering system should be used to maintain a uniform steering. Research results provide...
In order to increase reliability of brake system on FW6 underground engineering services vehicle, the dynamics performances of vehicles braking system in different conditions were analyzed by modeling and simulation on AMESIM platform through analysis its basic principle. The results show that the vehicle braking system can meet the braking requirements and the selected prefill accumulator can brake...
The process of multi-wedge cross wedge rolling precision forming is an advanced technology forming long-shaft parts, and its application is restricted because there are internal defects in the rolling process. The stress and strain of the feature points have been studied during multi-wedge rolling process by three-dimensional modeling and finite element simulation method and the stress and strain...
A virtual prototype model of vehicle, UA tire model and road spectrum model were established according to BT345J Articulated Dump Truck (ADT). The simulations of steering in situ and in steering in driving were carried out for ADT in ADAMS / VIEW platform. The varying rules of tire dynamic parameters under the two conditions were compared and analyzed. The results shows that the varying rule of lateral...
