A Study of Track and Train Dynamic Behavior of Transition Zone Between Concrete Slab Track and Ballasted Track
When a train is traveling along the transition such as slab and ballasted track, dynamic behaviors of rail system and train are abruptly changed. In R&D project, the newly-developed precast slab track system and track transition between slab and ballasted track was planned to construct in 2006 on the newly-built Jeolla-line. Maintenance demand, settlement and component degradation were predicte...
متن کاملSlab Track Design for High-speed
If the low-maintenance characteristics of slab track on open line are to be retained, great care must be taken to ensure that the subgrade layers are homogenous and capable of bearing the loads imposed [2]. The slabs can be precast or poured on site. The most known tracks with precast slabs are Shinkansen line in Japan and Max Bögl slab track designed in Germany [2], while as examples of the tr...
متن کاملDynamics of precursors to frictional sliding.
We measure the spatial and temporal behavior of the true contact area A along a rough spatially extended interface between two blocks in frictional contact. Upon the application of shear the onset of motion is preceded by a discrete sequence of cracklike precursors, which are initiated at shear levels that are well below the threshold for static friction. These precursors arrest well before tra...
متن کاملA Study on the Wheelset / Slab Track Vertical Interaction
This paper deals with the interaction between a moving wheelset and a slab track due to the shortpitch corrugated rail. The wheelset is modeled using a free-free Timoshenko beam with attached rigid bodies as the axle boxes, wheels and brake discs. The slab track model consists of elastically supported double EulerBernoulli beams. In fact, both wheelset and slab track are symmetric structures an...
متن کاملNetwork Theory, Cracking and Frictional Sliding
We have developed different network approaches to complex patterns of frictional interfaces (contact areas developments). Network theory is a fundamental tool for the modern understanding of complex systems in which, by a simple graph representation, the elementary units of a system become nodes and their mutual interactions become links. With this transformation of a system to network space, m...
