A project is being carried out by British Rail R & D Division to examine the feasibility of using active control to improve the performance of secondary suspensions for railway vehicles. Historically the project stems both from work on magnetically levitated vehicles (1) and from the Division’s involvement in tilt systems for the Advanced Passenger Train. The project began in 1978, and theoretical studies immediately showed that large improvements in suspension performance could be achieved, giving r.m.s. body accelerations of typically half those for a good passive suspension. To date the emphasis has been upon secondary suspensions, since it is controlling the transfer function of these that offers greatest benefits for ride and track forces. The project is not restricted to one particular vehicle, but involves investigating and developing suitable hardware for implementing active suspensions in general and also performing systems and application studies looking at the benefits to the railway business.
