The problem of vehicle–bridge dynamic interaction system under articulated high speed trains is studied in this paper. A dynamic interaction model of the bridge-articulated train system is established, which is composed of an articulated vehicle element model and a finite element bridge model. The vehicle model is established according to the structure and suspending properties of the articulat...

The hydraulic steering mechanism can lead the vehicle’s hydraulic system more complex and the tire wear heavier in the process of steering, which is detrimental to the steering control of the articulated motordriven vehicle. Thus the skid steering mode is implemented in the articulated motor-driven vehicle in this paper. This mode can simplify the vehicle without steering cylinder and it is mor...

Abstract This paper proposes SSM (Sensor Steering Mechanism) for a lateral guided vehicle with an articulated body. Authors demonstrated the simple lateral guiding method SSM for the front wheel steer type, the reverse phase four-wheel steer type and the rear wheel steer type vehicle. SSM presents the stable lateral guiding performance for automated vehicle which follows a straight and curved p...

This research was mainly focused on the evaluation of path planning approaches as a prerequisite for automation bale collection operations. A comparison between traditional approach using vehicles such tractors, and loaders with an optimized new autonomous articulated concept vehicle neighborhood reach capabilities (AVN) carried out. Furthermore, effects carrying capacity reduction in working d...

non-linear characteristic of tire forces is the main cause of vehicle lateral dynamics instability, while direct yaw moment control is an effective method to recover the vehicle stability. in this paper, an optimal linear quadratic regulator (lqr) controller for roll-yaw dynamics to articulated heavy vehicles is developed. for this purpose, the equations of motion obtained by the matlab softwar...

This paper presents the path tracking and following for the Autonomous LHD (Load-Haul-Dump) articulated vehicle. A fuzzy logic control system for the articulated vehicle was developed to control longitudinal and lateral motion. The lateral control keeps the vehicle along the planned path and the longitudinal control makes the vehicle running at the required speed. Fuzzy logic control method is ...
