“…The vehicle is driven by all wheels with independent wheel-side motors. Its steering motion is realized with the coupling effect of hydraulic struts and articulation joint, which have been introduced in literature [3,17]. In terms of the traditional design of AHVs, there is no suspension in the chassis system.…”

“…As the new mechanical equipment in mining industry, the distributeddrive articulated heavy vehicles (DAHVs) and its good vehicle performance become particularly important. However, due to the special structure of two vehicle parts connected by two hydraulic struts and one articulation joint without locking mechanism [3][4][5] , the front and rear vehicle parts can rotate relatively, which easily make DAHVs produce oscillatory yaw motion during moving process, especially with the external disturbance. Moreover, the hydraulic struts is inevitably entrained with gas and produce leaks, which can decrease the vehicle torsional stiffness and increase the oscillatory yaw motion or even lead to instability for DAHVs [6,7] .…”

This paper presents a differential drive approach for distributed-drive articulated heavy vehicles (DAHVs) with wheel-side motors. The objective is to keep the yaw stability for DAHVs with direct yaw moment in driving process when the external disturbance acts on one of the vehicle parts. Three contributions are made in this paper: 1) An disturbance observer based Extended Kalman Filter (EKF) strategy is implemented to deal with the unknown mismatched disturbances in strong nonlinear vehicle system for DAHVs; 2) The differential drive approach is developed with the guidance of model predictive controller (MPC) to cope with the vehicle instability with the decoupling dynamic analyses of DAHVs under the observed external disturbance and the specific drive limitation of wheel-side motor for the first time; 3) The novel verification techniques with co-simulation model combining with the ADAMS, Simulink, and AMESim software for DAHVs is employed to verify this vehicle stability controller, which is more reasonable than the traditional methods with simple virtual model. The results demonstrate that the proposed approaches can reduce the oscillation amplitude and period of vehicle yaw motion for about 40% and 80%, respectively. Moreover, the MPC strategy is more efficient comparing with the LQR strategy especially on boundaries issue treatment, which can improve the vehicle stability greatly.

The load sensing steering system of articulated loaders is prone to large pressure shock and oscillation during steering operations, affecting the stability of the steering system. To improve this phenomenon, an optimized structure of the redirector with by-pass damping is proposed, which adding orifices and throttle grooves to the original redirector. In the study, to control the steering load and working conditions, the steering load of the loader is replaced by using a pressure regulating valve. The simulation and experimental results shows that, compared with the traditional redirector, using the novel structure redirector with by-pass damping ensures good load sensing characteristics, the peak output pressure shock caused by the load unit step signal decreases from 65.04bar to 56.35bar, with a decrease rate of 13.4%, reducing the pressure oscillation of the hydraulic system. The pressure fluctuation time can be reduced from 2.09s to 1.6s, with a decrease rate of 23.4%, the output pressure oscillation decays faster, the smoothness of the steering operation is significantly improved.
