Temperature Variation Characteristics and Effects of Stiffness of Fastener Rubber Pads in Extremely Cold Conditions
The article uses a universal testing machine equipped with a temperature control box to analyze the temperature variation characteristics of the stiffness of the fastener rubber pad under extreme cold conditions.Through a vehicle track coupling dynamic model,the influence of the stiffness of the fastener rubber pad on the dynamic response performance during high-speed railway operation is described.Finally,using the field of view analysis method,the influence of fastener pad stiffness on the acceleration change rate,wheel load reduction rate,and wheel rail vertical force of high-speed railway trains under extremely cold and normal temperature conditions is completed,and corresponding suggestions are proposed accordingly.
