Computational Railway Dynamics
2007High-quality and efficient means of transport is of high priority in the modern society. Railway traffic is environment friendly and economically very competitive for both freight and personal transports at mid-range distances. Although the railway technology has been improved substantially during the last decades, generated vibrations still impose ...

IFAC Proceedings Volumes, 2003
Abstract From an example formal (ie., computing science based) model of railway nets, their rail units and the various forms of states of these rail units, we put forward some suggestions for future research & development that engages researchers of automatic control and computing science in collaborative work.

The impact of railway development on urban dynamics
2008This book addresses the role of railways in urban development. Our central aim is to inquire into how the renaissance of railways since the end of the 20th century (especially the development of high-speed rail and light rail links) will affect European cities.

System Dynamics for Railway Infrastructure Protection
2013The railway infrastructure represents, for its symbolic value and accessibility, a very attractive target for criminals and terrorists alike. This paper intends to address the security issues of such systems, beginning with the railway stations themselves., The peculiarities of the railway infrastructure, in terms of geographical dispersion and mass ...

Simulation of Railway Vehicle Dynamics
2019This chapter covers the basic methods used in setting up a model of a typical railway vehicle and the types of analysis that can be carried out once the equations of motion have been produced. The historical development of the major simulation packages now used is also briefly covered. Typical analysis tasks such as modal analysis and running stability,

Dynamics of a model of a railway wheelset
Nonlinear Dynamics, 1994In this paper we continue a numerical study of the dynamical behavior of a model of a suspended railway wheelset. We investigate the effect of speed and suspension and flange stiffnesses on the dynamics. Numerical bifurcation analysis is applied and one- and two-dimensional bifurcation diagrams are constructed. The onset of chaos as a function of speed,

A Bio-Inspired Approach for a Dynamic Railway Problem
Ninth International Symposium on Symbolic and Numeric Algorithms for Scientific Computing (SYNASC 2007), 2007We consider the railway traveling salesman problem, denoted RTSP, in which a salesman using the railway network wishes to visit a certain number of cities to carry out his/her business, starting and ending at the same city, and having the goal to minimize the overall time of the journey.

Dynamics of Vehicles on Railway Bridges
Vehicle System Dynamics, 1975Several mechanical models have been developed to simulate the dynamic action of railway vehicles moving along railway bridges. Vehicles are very complex mechanical systems with a number of degrees of freedom, linear and non-linear springs and damping. Modern vehicles possess also clearly differentiated unsprung and sprung masses.

A History of Railway Vehicle Dynamics
2006The railway train running along a track is one of the most complicated dynamical systems in engineering, with many degrees of freedom and a moving interface that connects the vehicle to the track. The dynamics of this complex system has a long history, and this chapter tells the story of its conceptual and analytical development, concentrating on the ...
