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.

As the development of urbanization and economy, the traffic stresses in most urban cities in China have many severe challenges that need solving in the process. The idea of a new kind of streetcar based on virtual tracks which owns a series of advantages including suitable speed, big capacity, low construction cost and environmentally friendly is proposed. The designation of the streetcar is moving around the aim of a capacity of 15 thousand persons per hour with the operation speed of 40~50km/h. The key technologies are consists of the identification and navigation of the virtual tracks, differential steering theory, vehicle system dynamics, suspension system, precise control of wheel hub motor and the right of way rules (ROW). This article describes technical principles of each key technology and their latest development in the progress of the green streetcar based on virtual tracks.

“…Therefore, the tramcar, as a new urban transport system, has been widely used around the world. 1,2 By using independently rotating wheelsets (IRWs), the tramcar can achieve low-floor design, which is helpful for facilitating the use and reducing the operation time. However, the rolling radius difference of the two wheels of an IRW no longer generates the yaw torque, which is primarily obtained from the longitudinal creep forces and is required for the self-guidance and steering.…”

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.
