<b>Recent Research on Railway-specific Dynamic Issues</b>

چکیده
Railway system is composed of many sub-systems such as overhead contact lines, vehicles, tracks and structures, which interact with each other show complex dynamic behaviors. We are working on the elucidation countermeasures for railway-specific phenomena caused by interaction sub-systems, damage due to natural disasters, train running safety, deterioration using our own simulation experiment/measurement technologies. This report introduces examples recent research in field railway dynamics, related improvement resilience against digitalization structure maintenance, hybridization OCL/pantograph simulation, weight reduction car bodies.

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 کاملrailway network timetabling and dynamic traffic management
the paper discusses the current state of research concerning railway network timetabling and traffic management. timetable effectiveness is governed by frequency, regularity, accurate running, recovery and layover times, as well as minimal headway, buffer times and waiting times. analytic (queuing) models and stochastic microsimulation are predominantly used for estimation of waiting times and ...

متن کاملResearch on Modeling and Simulation for Railway Transportation System
This paper studies the modeling theories and simulation methods for railway transportation system. The railway transportation system is a typical temporal-spatial dynamic system. Recently the method with temporal-spatial computation characteristics, Cellular Automata, is often used for road traffic flow research, but it’s homogeneity restricting make it impossible to modeling railway transporta...
متن کاملStatic and Dynamic Analyses of Micropiles to Reinforce the High Railway Embankments on Loose Beds
Construction of railway embankments on loose beds without using any methods of soil improvement (e.g. stone columns in silt and clay beds, deep soil mixing method, jet grouting and also using micropiles individually or in groups form) leads to reduction of embankment slope gradient, which significantly increases the volume of soil operation. Generally, micropile as a reinforcing element with t...
