In order to suppress the vertical bending vibrations of railway vehicles, vibration characteristics of a car body have been investigated under a vibration test. It was however not possible to evaluate the level of riding comfort with a conventional exciter due to the shortage of power in the performance. We therefore have developed a powerful and lightweight exciter capable of vibrating a car body at site, and an analytical technique of signal processing to evaluate ride comfort. This paper describes an analytical technique and the vertical exciter, by which vibration characteristics and riding comfort can be evaluated at the stationary test. This analytical technique adopts a way of synthesizing FRF, by which the level of ride comfort can be estimated. This exciter uses a linear magnetic actuator. The exciter fixed on an axle box is used with wheelset support device. We confirmed that this exciter has sufficient capability of vibrating a car body under the vibration test.
