“…Te Mark 4 passenger train of UK rails always has a very serious wheel wear problem [7]. Starting from the relationship between the rational RRD curve of the wheelset and the lateral even power dissipation on tread [41], literature [42] proposed the following solution, i.e., incorporating hydraulic damping in the bogie primary suspension, such as a hydraulic joint of axle box rotating arm with the higher technical risk. As mentioned above, the self-adaptive improved design of a higher-/high-speed bogie should solve the difcult problem of detrimental wear at the minimum cost.…”

HSRS is taken as a typical research case of large-scale complex nonlinear systems, and the re-innovation of associated imported technologies needs to be combined with the particularities of Chinese HSR practices, seeking a more suitable dynamic design methodology to conduct the self-adaptive improved design. Different from the troublesomeness of the primary hunting phenomenon, the self-adaptive improved design can decrease considerably the impact of car body instability on ride comfort merely by applying the semiactive damping technique between intervehicles, to promote scientifically the limit and construction speeds under the rational conditions of wheel-rail matching, i.e., λeN ≥ λemin, λemin = (0.03–0.05). The researching viewpoint of hunting kinematics makes the investigations on the geometric nonlinearity of the wheel-rail contacts contrary to the hypothesis of small creepage and no spin. Since the technical prototype of German ICE3 serial bogies has the design default of the primary hunting phenomenon, the improved design of the wheel-rail relationship has simply abandoned the high-quality technical resources of wheel-rail matching conditions at low conicity. On the contrary, the dynamic simulation analyses of MC01-TC02-MC03 three-vehicles trainset show that the semiactive damping technique between intervehicles takes advantage of Izz >> Ixx to improve the impacts of car body instability on ride comfort, and the self-adaptive improved design has consequently the ability to achieve the technical goal of uniform wear at low conicity. On the premise of meeting the requirements of crossing over different speed grade dedicated lines and realizing the running operations on three-speed levels of 160/250/350 km/h, the self-adaptive higher-/high-speed bogies can conditionally satisfy the economic reprofiling requirements of wheelsets through the optimal routing planning.

“…The first one, the so-called macro approach, is based on global equilibrium considerations. Accordingly, the power losses are calculated by considering the negative work done by the total generalised forces exerted at the tyre-road interface (longitudinal, lateral and self-aligning moment) for their dual entities (longitudinal, lateral and spin slip, respectively) [12,13]. This approach has the advantage of being low-computationally costly, and therefore is often preferred when it comes to vehicle-dynamics simulations [14].…”

Tire slip losses have been shown to have a significant impact on vehicle performance in terms of energy efficiency, thus requiring accurate studies. In this paper, the transient dissipation mechanisms connected to the presence of micro-sliding phenomena occurring at the tire–road interface are investigated analytically. The influence of a two-dimensional velocity field inside the contact patch is also considered in light of the new brush theory recently developed by the authors. Theoretical results align with findings already known from literature but suggest that the camber and turn spins contribute differently to the slip losses and should be regarded as separate entities when the camber angle is sufficiently large. The present work shows that an additional amount of power which relates to the initial sliding conditions is generated or lost during the unsteady-state maneuvers. A simple example is presented to illustrate the discrepancy between the microscopic and macroscopic approaches during a transient maneuver.

“…Huang et al 13 established an analytical model for accurately determining the contact position and a slice-based model to calculate the contact stress on a contact point, making the calculation more accurate. Alarco´n et al 14 studied the influence of the friction coefficient varying from 0.2 to 0.7 on the power dissipation model in the wheel-rail contact. Ma et al 15 proposed a novel modeling strategy: 3D explicit finite element analysis was associated with 2D geometrical contact analysis and an adaptive mesh refinement technique, which was able to achieve a good balance between accuracy and calculation efficiency.…”

Wheel and rail wear seriously affects the safety and reliability of train operations. In this study single-carriage and double-carriage models considering the connecting unit of a high-speed train are developed to investigate the normal forces, lateral forces, and lateral displacements of wheelsets. Based on the results from these models, the Archard wear model is employed to predict the wheel wear. In addition, based on the daily measured data, a nonlinear autoregulatory (NAR) model and a wavelet neural network (WNN) model are developed to predict the wheel wear over a longer time period. The simulation results show that, compared with the single-carriage model, the normal forces, lateral forces, and lateral displacements of the wheelsets close to the connecting unit in the double-carriage model increase to a certain extent dependent on the speed. The wheel wear predictions show that the wheel wear on the wheelsets near the connecting unit is slightly larger than on the wheelsets far from the connecting unit. Based on the mean square error, the NAR model has somewhat better performance in the wheel wear prediction than the WNN model. The research results represent an important contribution to the maintenance and safe operation of high-speed trains.
