The Fatigue Test of Railway Rail Fastener Assemblies

Abstract:

The rail fastener assemblies under alternating load for a long time , in addition to the vibration and strength,fatigue also is the main reason for damage .So effective fatigue test and life assessment is one of the important means to ensure the safety of railway operation .This paper introduces the routine fatigue test method of railway track fastener assembly which adopts the European Railway Standard EN13146-4,by using 33° test platform which conform to the actual operation stress conditions of the railway track can more effective test the rail fastening assembly.
