This thesis covers an experimental study on the exciting force created by a train and a method for measuring this force, concentrating on the characteristics of the exciting force, which are some of the fundamental factors in the system creating the solid-borne sound, and which are generated between the rails and the train wheels, for the purpose of controlling the noise transferred from the track to the structures built above the track. As a result of the study on the methods for measuring the exciting force, we came to the con clusion that, though both the direct measuring method (in which the force sensor is used) and the transfer function method, the indirect method (in which the force calculation is made from the response function in the transfer system), are effective, the former is more suitable when precise measurement of the exciting force in the low-frequency range is required. The exciting force generated when a train travels over flat track can be predicted to have exciting-force characteristics within a frequency range below than 63 Hz, taking the train's overall mass/speed and the rail resonance caused between the sleepers into consideration.
