Dynamic Behavior in Transition Zones and Long-Term Railway Track Performance
نویسندگان
چکیده
Transition zones between embankments and bridges or tunnels are examples of critical assets the railway infrastructure. These locations often exhibit higher degradations rates, mostly due to development differential settlements, which amplify dynamic train-track interaction, thus further accelerating settlements deteriorating track components vehicles. Despite technical scientific interest in predicting long-term behavior transition zones, few studies have been able develop a robust approach that could accurately simulate this complex structural response. To address topic, work presents three-dimensional finite element (3D FEM) tracks at zones. The considers both plastic deformation ballast layer using high-cycle strain accumulation model non-linearity vehicle-track interaction results from evolution deformed states itself. shed some light into evidence response structures its interdependency with transient interaction. Aspects when assessing performance these systems analyzed detail, might be relevance for researchers practitioners design, construction, maintenance processes.

Dynamic Analysis of Railway track
In the present analysis, an infinite Euler– Bernoulli beam of constant cross-section resting on an elastic foundation is considered. The beam and foundation are assumed to be homogeneous and isotropic. The foundation is modeled using one parameter without damping. The beam is subjected to a constant point load moving with a constant speed along the beam. An effort has been made to find the solu...

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...
