The aim of this paper is to investigate the possibility of improving the ride quality of a two-axle railway vehicle with a single-stage suspension by means of passive suspensions employing an inerter device. The inerter is a mechanical one-port element that is analogous to a capacitor in electrical circuits. The goal is to improve the ride quality in both the vertical and lateral motions in response to track irregularities. Performance benefits for several simple passive suspension layouts are demonstrated and compared with the conventional scheme. The elastic effects of the damper and inerter device are then taken into consideration for practical purposes. The optimum parameter values of the damper, inerter and the parameters representing the elastic effects provide guidance for mechanical design purposes

“…Inerter concepts have been successfully applied to vehicle suspensions (Wang and Su, 2008;Wang et al, 2009aWang et al, , 2012Wang and Liao, 2010;Wang and Chan, 2011;Jiang et al, 2012Jiang et al, , 2013 and building structures (Wang et al, 2010a) to suppress vibrations. At present, we have proposed four inerter prototypes: the rackpinion inerter (Wang and Smith, 2004), the ball-screw inerter (Wang and Su, 2008), the hydraulic inerter , and the mechatronic inerter network (Wang and Chan, 2011).…”

This paper applies a newly developed mechatronic inerter network to suppress vibrations of a full optical table. Optical tables are normally applied to insulate precision machines from two types of disturbances: ground disturbances from the environment and load disturbances from the equipment. These two disturbances can be independently controlled by disturbance response decoupling (DRD) techniques. For example, we can isolate the ground disturbances by soft passive suspensions and improve the load responses by active control. However, the passive elements cannot be easily adjusted according to the operating conditions. Therefore, this paper applies mechatronic inerter networks to a full optical table, and optimizes the ground responses by connecting the networks to suitable electric circuits. We then apply DRD techniques to improve the load responses without influencing the ground responses. The designed mechatronic inerter networks and active controllers are implemented to a full optical table for experimental verification. Based on the results, the proposed mechatronic inerter networks and DRD structures are deemed effective in improving system responses.

Abstract. In this paper we study the dynamics of two degree freedom system, which is consist of main body and tuned mass damper with inerter (TMDI). We add the dash-pot with variable damping coefficient to TMDI to study the overall efficiency of the device. The shape of non-linear characteristic of the dash-pot is dependent on one control parameter which governs the steepness of the function and the value of damping coefficient changes according to the relative displacement or velocity between main mass and tuned mass damper. We show the two parameters diagrams showing the maximum amplitude of the main body versus frequency of excitation of main body and controlling parameter.
