Elastic system for vibration level reduction

Abstract

In this paper one presents the process of designing an elastic system consisting of elastic plates / slates inlaid between rail and sleeper / support plate, between support plate and sleeper, between sleeper and boxing material and between cover plate and concrete platform. Elastic plates / slates absorb vibrations / noises from railway tracks. These vibrations propagate in railway tracks as well as in the basic structure of railway and civil construction foundations in the surrounding area. Concrete railway sleeper are rigid compared with steel sleeper or still timber and so it need impact attenuation. In subway area the noise and vibrations levels are an important issue. This project is applied in SC Metrorex SA Bucharest subway network.
