| 英文摘要 | Nowadays, the sleeper, railroad bed, welding technology and materials of the high-speed & heavy-load Continuous Welded Rail (CWR) have been improved greatly. However, the orientation relationship between welding surface and rail is still orientation structure, which appeared 185 years ago in UK, namely, the welding surface is normal to the longitudinal direction of the rail. Thus rail welds are subject to vertical pure shear stress, lateral pure shear stress and axial pure tensile stress. Pure shear stress and pure tensile stress are both dangerous stresses, which result in failure of welds under high-speed & heavy-load condition for a long time. When the wheels pass rail welds, it is difficult to avoid vertical bumping and lateral vibration. In order to solve these problems, in this paper we put forward the single inclined welding surface having dip angle alpha with the lateral rail or dip angle beta with the vertical rail and analyze the position geometry and stress state. Thus the vertical bumping and lateral vibration are basically eliminated, then the bearing capacity of the welding surface is significantly improved, and the stress of axial pure tensile and lateral pure shear of the welding surface is reduced. |
