متن کاملNumerical Modeling of Railway Track Supporting System using Finite-Infinite and Thin Layer Elements
The present contribution deals with the numerical modeling of railway track-supporting systems-using coupled finite-infinite elements-to represent the near and distant field stress distribution, and also employing a thin layer interface element to account for the interfacial behavior between sleepers and ballast. To simulate the relative debonding, slipping and crushing at the contact area betw...
متن کاملSquare Joints in Railway Track Waves
When rails are laid in a railway track, small gaps are left between the ends of adjoining rails to allow for the expansion of the rails when the temperature rises. Rail joints are provided to form a continuous rail path which are normally laid in standard lengths bolted together by fishplates. When two rail joints are exactly opposing each other, they are called square (side by side) joints...
متن کاملInvestigating the Behavior of Railway Sleeper for Different Cases and Track Conditions by Using Analytical and Numerical Methods
Railway Sleepers are one of the most important elements in the track superstructure. Their tasks are keeping the track geometry, resisting against vertical and lateral train loads and transferring the train loads to the ballast layers. In this research, the railway sleeper as a beam on the elastic foundation is modeled with finite length. In this regard, two cases including a) beam with constan...
