In this study, an active suspension system with multiple non-identical delayed resonators (DR) is proposed in order to, suppress vibrations that are caused by railway track irregularities. Mathematical models for a railway vehicle and track irregularities are given. In addition to this, methods on choosing the physical parameters and the design steps of multiple DR are mentioned. Simulations using the approximate mechanical parameters of a Shinkansen SKS300 train are made. Results and comparison with other methods are also given to evaluate the success of the proposed method.
