“…The motors can be externally mounted and connected to the wheelset through a gearbox (Pérez et al [137], Liang et al [139,140], Ahn et al [141], Lu et al [142] and Farhat et al [98,143]) as shown in Fig. 30 or embedded inside the wheels (Mei et al [144], Ji et al [145] and in the 'Next Generation Train' project in [124], [146][147][148][149]). The absence of additional actuators leads to a reduction in the space required by the wheelset frame, and to the possibility to provide both traction and control within the same system reducing cost and improving reliability.…”

“…This approach is generally applied to DIRW where additional feedback variables may be introduced. Within the 'Next Generation Train' project, a PD control was used by Kurzeck et al [146] to implement the zero lateral clearance approach. In his study, Kurzeck focused on the peak torque and power required due to track irregularities.…”

Since the concept of active suspensions appeared, its large possible benefits has attracted continuous exploration in the field of railway engineering. With new demands of higher speed, better ride comfort and lower maintenance cost for railway vehicles, active suspensions are very promising technologies. Being the starting point of commercial application of active suspensions in rail vehicles, tilting trains have become a great success in some countries. With increased technical maturity of sensors and actuators, active suspension has unprecedented development opportunities. In this work, the basic concepts are summarized with new theories and solutions that have appeared over the last decade. Experimental studies and the implementation status of different active suspension technologies are described as well. Firstly, tilting trains are briefly described. Thereafter, an indepth study for active secondary and primary suspensions is performed. For both topics, after an introductory section an explanation of possible solutions existing in the literature is given. The implementation status is reported. Active secondary suspensions are categorized into active and semi-active suspensions. Primary suspensions are instead divided between acting on solid-axle wheelsets and independently rotating wheels. Lastly, a brief summary and outlook is presented in terms of benefits, research status and challenges. The potential for active suspensions in railway applications is outlined.

“…The PID method was also used to design the controller to achieve stability and steering control of rail vehicles with IRWs. 13 The German Aerospace Center (DLR) 14 is trying to use a PD controller with actuation limitation to achieve active guidance and perfect radial steering by controlling the torque applied on the IRWs. As a tramcar is a complex and nonlinear dynamic system, the classical P, PD, or PID control algorithm cannot achieve the optimal control effect, although the steering ability of the vehicle can be improved to a certain extent.…”

This paper presents a robust active guidance controller that uses the µ-synthesis method to improve the ability of guidance and to reduce the wheel–rail wear under the consideration of system nonlinearity, parameter uncertainty, and measurement noise in tramcars with independently rotating wheelsets (IRWs). Each wheel of the tramcar is connected to a sider motor, and the active yaw moment is generated by the torque differences between the left and right wheels in the same axle. To achieve local control, the wheel–rail force and the primary suspension force are considered as external disturbances, and the IRW state–space model is modeled independent of the tramcar system. The effectiveness of the controller is mainly verified by the cosimulation method: the dynamic model of the tramcar is established in SIMPACK, and the controller model is established in MATLAB. The simulation results show that compared with the passive case, for the actual tramcar, the control method can improve the vehicle's running performance and can significantly reduce the wheel–rail wear in both straight and curved tracks. A 1:5 scaled tramcar model is used for the active guidance experiment to further verify the effectiveness of the algorithm.

“…12) The NGT running gears use so-called independently rotating wheel sets (IRW set) with two wheels attached to a wheel carrier. Active guidance control (Kurzeck et al, 2014) provides running stability and low wear properties of this configuration which is a main objective of the NGT project.…”

High crosswinds affect the stability of railway vehicles, in particular if they run on very high speed to reduce traveling time, if they are configured as double-deck cars to increase the number of passenger seats and if they use lightweight design in order to reduce life-cycle costs. This is why crosswind stability is an active field of research within the project Next Generation Train. However, this field relies on the cooperation of two different domains, namely aerodynamics and vehicle dynamics. With this background a crosswind stability tool was implemented in Modelica as a part of the DLR RailwayDynamics Library. This tool gathers data from scaled wind tunnel measurements and multibody data on the railway vehicle in order to rapidly analyze and assess the risk of overturning due to high crosswinds. To a large extent the tool is oriented towards the associated homologation rules and standards. However, the tool is as well supposed to support future advancements of these standards by providing capabilities for the stochastic analysis of the crosswind stability problem.
