“…On-track tests of a vehicle with active vertical secondary suspensions were reported by Qazizadeh et al [36,37]. Here, secondary lateral and vertical dampers were replaced by electro-hydraulic actuators on the high-speed train Regina 250.…”

“…Moreover, the lateral acceleration of the bogie is low-pass filtered and half the bogie mass is used as gain to form the force reference for HOD function. The idea of modal control is also applied in the studies by Hammood and Mei [33], Sugahara et al [34], Yusof et al [35], and Qazizadeh et al [36,37].…”

“…Figure 13 gives the workflow for sky-hook damping. Thanks to the simplicity of sky-hook control, it is the one that finds application in full-size vehicle tests (Qazizadeh et al [36,37] and Sugahara et al [39,40]). In scientific studies, the sky-hook control is also used as reference to prove the effectiveness of other refined control techniques by Gopala Rao et al [41], Sugahara et al [39], [40], Pacchioni et al [42] and Orukpe et al [43].…”

“…KTH and Bombardier Transportation in Sweden have explored and developed active suspension in the program Green Train since 2005 [73]. Active lateral suspension and active vertical suspension were implemented on Regina 250 trains and tested in the line from 2007 to 2013 [31,37,74]. The HOD function was incorporated in the suspension to centre the car-body above the bogies in curves.…”

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.
