Rubber components are widely used in rail vehicles for vibration damping and positioning, which have the functions of compact structure, easily adjustable stiffness, light weight, no wear and tear, non-linearity, and both vibration damping and vibration isolation. With the rapid development of high-speed trains, high-power locomotives, heavy-duty speed wagons and urban rail transit vehicles, promoting the use of high-performance elastic components in a large number of railway vehicle bogie suspension system. The wide application of rubber components can improve the stability, smoothness, comfort and safety of vehicle operation, reduce operational noise, reduce wear parts and wear parts, reduce wheel and rail wear. However, for example, if the rubber components of bogie are under continuous alternating load for a long time, fatigue fracture is the main failure mode, and the fatigue fracture of the key components will lead to major safety accidents.

Based on our years of research and development of long-life rubber vibration damping products for aviation, it is of great significance to introduce the relevant technology into the development of rubber components for rail vehicles, which is of great significance to improve the fatigue life of rubber components, and the life span of the relevant products developed has been significantly improved, which significantly reduces the whole life cycle cost of customers.
