Abstract

In this paper, the process of development of resilient sleepers, which improves the train safety, passenger comfort and reduces the noise and vibration, is presented. To optimize the bonding method between elastic pad and PC sleeper, special pad shape like arrow is adopted and is applied in manufacturing. Bonding strength and reduction effects of vibration of the resilient sleepers are experimentally investigated. From the experiment results, it is investigated that the bonding strenth is enough to satisfaction the criteria and the vibration characteristic is also more effective for sleeper with elastic pad than that in ordinary PC form. These results indicate that the elastic pad can reduce possibility of rail-corrugations and thus resulting in the reduction of maintenance costs.
