METHOD FOR IMPROVING FATIGUE RESISTANCE PERFORMANCE OF LOCOMOTIVE RUBBER-METAL PAD WITH VARIABLE THICKNESS AND LOCOMOTIVE RUBBER-METAL PAD

摘要

A method for improving fatigue resistance performance of a locomotive rubber-metal pad with variable thickness improves the fatigue resistance performance of the rubber-metal pad and prevents rubber and metal from being torn during running by changing a structure of the rubber and the metal of the rubber-metal pad and adjusting a shape and position relationship between the rubber and the metal. The shape and the position relationship of the rubber metal is adjusted by adjusting thickness of a rubber layer between the rubber and the metal of the rubber-metal pad so that the rubber layer has variable thickness. The fatigue resistance performance of the rubber-metal pad is improved by adjusting the thickness of the rubber layer.
