Rail Track Isolation

A Proven Mass-spring System for Achieving Very High Levels of Noice & Vibration Isolation.

Rail rapid transit systems, especially those underground sections can produce ground-borne vibrations and noise from the moving train, which is transmits to surrounding buildings. This effect can be minimized by isolating the vibration via the use of floating-slab track bed. As the name itself suggested, the concrete slab track bearings (FST bearings), which acts as a rubber spring in some sense to isolate the vibration from the train movement to the nearby structures. Usually, the preferred FST bearings are made from natural rubber.

Since the efficiency and effectiveness of the vibration isolation is sensitive to the ‘spring stiffness’ of the FST bearings, Doshin is committed to provide customized design and prototype development as well as testing to meet the given specifications given by our clients.
