DYNAMIC VARIATION OF WHEEL LOAD ATTRIBUTED TO VERTICAL DEFORMATION OF RAIL END

Vertical deformation of rail end within the allowable tolerance when supplied from manufacturer often causes unevenness of running surface of rail at welded rail. The transient vibration caused by this local unevenness at welded part was theoretically discussed for the vehicle-track vibration system. The relationships among train speed, length of unevenness, spring coefficient of rail support, damping coefficient of rail support and dynamic variation of wheel load were discussed.
