Managing the wheel–rail interface: the Japanese experience

摘要: Abstract: Rolling contact fatigue (RCF) defects such as squats or surface shellings; gauge corner cracks head checks; face wear; rail corrugations which have four types classified from the viewpoints of mechanism and occurrence location; friction/adhesion are related to wheel flange climb derailment in sharp curves, stability high-speed operation braking performance case wet wheel–rail interface conditions; lubrication improve steering bogies reduce wear corrugations; grinding prevent RCF recover configuration – there very important issues Japanese railways, this chapter describes current status experience them.
