Cellentic Rail Pads and Baseplate Pads Reduce Vibrations and Structure-borne Noise

Cellentic rail pads and baseplate pads are currently being used to reduce structure-borne vibrations and vibrations in two applications from the field of local public transport by rail. These applications are used in the metro network of Budapest, which has a total length of 33 km with 42 stations. The applications are also used in the city of Bangkok in China, where there are two different operators of rail-guided local public transport. The article discusses how modern rail-fastening systems offer the necessary elasticity to ensure that forces due to eccentricities in the wheels or irregularities in the rails do not lead to excessive wear or damage. A material called cellentic is a key component used to reduce structure-borne noise and this material is applied in the form of rail pads and/or baseplate pads. Because of its’ porous structure, the highly elastic microcellular ethylene propylene diene monomer (EPDM) prevents vibrations from getting to the substructure. The chemical composition of the cellentic has a saturated poly chain that provides a high level of resistance to chemical attacks. The article discusses how microcellular and baseplate pads that are made from cellentic retain their original shape even when subjected to loading.
