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

摘要

A method for improving fatigue resistance performance of a locomotive rubber-metal pad with variable diameter and a locomotive rubber-metal pad, which 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 position relationship between the rubber and the metal is adjusted by adjusting a size of a rubber layer diameter between the rubber and the metal of the rubber-metal pad so that the rubber layer diameter of each layer is a variable diameter; and the fatigue resistance performance of the rubber-metal pad is improved by adjusting diameter of rubber layers.
