“…Based on this idea, some schemes of steering bogies by means of passive linkages or coupling of wheelsets have been proposed. Well established is for example the design of Talgo [106]. However, theoretically this control concept produces perfect curving behaviour only when cant deficiency is zero which seldom is the case in real operation.…”

“…Additionally, if the use of two-axle railway vehicles is considered together with IRWs, as described by Kurzeck and Valente [124] for the 'Next Generation Train' (NGT) project, a double-deck train set configuration with continuous low floor is possible. One of the first applications of IRW was presented in 1941 by Talgo in which passive steering capability was achieved by linkages between wheels [106]. Talgo's first solution is shown in Fig.…”

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.

“…In order to study the dynamical behaviors of tilting trains with low computational costs, the basic mechanisms of the tilting train were described by some constrained equations. Simplified models were then proposed to account for the dynamical couplings between compartments subjected to the articulated configuration of the Talgo trains [52]. PID-fuzzy-logic multi-objective tuning approach was also proposed for improving the performance of tilting trains in [53].…”

Research and development on high-speed railway systems and particularly its automatic control systems, are introduced. Numerical modeling of high-speed trains in the Chinese high-speed train system and its associate automatic control systems are described in detail. Moreover, modeling and simulation of train operation systems are analyzed and demonstrated.ince the first-ever high-speed train, the Japanese Tokaido Shinkansen, started operation at the maximum speed of 210 km/h in 1964 [1, 2], railway systems have gone through a rapid evolution and improvement with significant growths, mainly in Japan, Abstract © DIGITAL VISION & WIKIMEDIA COMMONS

“…The main reasons for not showing these results are other than lateral dynamics co-ordinates dynamical quantities particular authors are interested in or velocities below the critical one. Example publications of such type are [30][31][32][33][34][35][36][37][38]. The interesting subgroup within such publications are those based on vehicle-track models simulation, which use dynamical approach, but not the traditional engineering one, to search for proper, best or even optimum shape of TCs.…”

In this paper recent simulation results aimed at studying nonlinear phenomena that accompany motion of railway vehicle in transition curve at velocities around the vehicle critical velocity are presented by the authors. Such results concern six different objects representing railway vehicles. These are: three 2-axle railway bogies, two 2-axle railway cars, and 4-axle railway car. The paper attention is devoted to presenting as many different nonlinear behaviours of the studied objects as possible. This is done first of all to give an idea to the readers of great number of the nonlinear behaviour types that can appear for railway vehicles in transition curves at velocities lower and bigger than vehicle critical velocity. The differences arising from specificity of particular objects are highlighted while systematic variation of the system parameters in order to study influence of such variation on differences in the behaviour is less represented. The paper ends with the comprehensive comments by the authors to the results obtained.
