The FFLM vehicle system, in which a flip-flop linear motor with permanent magnets is used for propulsion, has been investigated. In this system, trucks are to be coupled as in a train and the basic function of a conventional railway wheelset is separated into 3 functions of support, guidance and propulsion. The running wheel, which is an independently rotating one, functions for support, the guide wheel for guidance and the FFLM for propulsion. Up to now, there have been no conventional railway vehicles employing coupled trucks. Thus, the effects of couplig trucks on train vibration have not becn examined. This paper concerns numerical analysis of the effects of coupling trucks on the lateral vehicle vibration, which is induced by lateral irregularities of the guide rail. The main results obtained are as follows. The lateral stiffness of the coupling at a position lower than the truck's center of gravity can reduce the lateral vehicle accelerations and the guide-spring distortion. The longitudinal stiffness between trucks has almost no influence on the lateral vibrations. The coupling of trucks has little influence on the vibration excited by cross-level irregularities of the running rail.
