Study on Possible Application of Rubber Granulate from the Recycled Tires as an Elastic Cover of Prototype Rail Dampers, with a Focus on Their Operational Durability

Abstract

This study is an attempt to investigate possible applications of rubber granulate SBR (styrene-butadiene rubber) produced from recycled waste tires as an elastic cover for prototype rail dampers, which are aimed at reducing the level of railway noise emitted in the environment. The authors present laboratory procedures and discuss the results of several experimental tests performed on seven different SBR materials with the following densities: 1100, 1050, 1000, 850, 750, 700 and 650 kg/m3. It is proven that rubber granulate SBR produced from recycled waste tires, can be used as an elastic cover in steel inserts in rail dampers, provided that the material density is not lower than 1000 kg/m3. In the conducted tests, samples of the materials with high densities exhibited good static and dynamic elastic characteristics and had sufficient operational durability.

Research on the Friction Noise Generation Mechanism and Suppression Method of Submarine Rubber-Based Propeller Bearings—A Review

“…Therefore, they have been widely used in submarines. In addition, like rubber tires, rubber-based propeller bearings can also be recycled for vibration reduction and ballast protection in railway traffic [ 2 , 3 , 4 , 5 , 6 , 7 ], which not only reduces economic costs but also contributes to environmental protection.…”

Field Measurement Analysis and Control Measures Evaluation of Metro Vehicle Noise Caused by Rail Corrugation

“…However, rail corrugation will appear in a certain period after grinding [24]. A rail damping was also studied to renovate rail corrugation [25,26]. The rail damping is found to be able to suppress the pinned-pinned resonance, and thus its use may lead to attenuating the development of short pitch rail corrugation [27].…”
