Rapid Risk Assessment of Technical Systems in Railway Automation
The European Railway Agency (ERA) has the challenging task of establishing Common Safety Targets and Common Safety Methods throughout Europe. In this context, the harmonization of risk assessment methods is also discussed. The purpose of this paper is to present a new approach to risk assessment of technical systems in railway automation, which allows a rapid risk assessment while at the same t...
متن کاملLateral Stability Analysis of High-Speed Railway Vehicle on Curve
A vehicle body, two bogie frames and two wheelsets for each bogie frame are used to describe the railway vehicle model. The system dynamic is modeled using a 38-DOF system including the longitudinal, lateral, vertical, roll, pitch and yaw displacements. A heuristic nonlinear creep model and the elastic rail are used to simulate the wheel-rail contact. Stable movement and the corresponding limit...
متن کاملBifurcation Analysis of High-Speed Railway Vehicle in a Curve
In order to prevent unpleasant incidents, preservation high-speed railway vehicle stability has vital importance. For this purpose, railway vehicle is modeled using a 38-DOF. This paper presents an investigation on limit cycle and bifurcation of high speed railway behavior. It is revealed that the critical hunting speed decreases by increasing the wheel conicity. Also the critical hunting speed...
متن کاملStatistical Analysis of the Railway Accidents Causes in Iran (TECHNICAL NOTE)
The occurrences of accidents on the railways are inevitable in today’s world and the factors which may cause it, except the atmospheric and accidental ones, are identified and preventable as well. Therefore, these factors can be investigated and useful actions can be performed in order to reduce these accidents. The main impetus of the present research is the statistical analysis of the causes ...
متن کاملRailway Vehicle Dynamics, Multibody Systems, and Bifurcation Analysis
DLR’s Vehicle System Dynamics group has a long tradition in the computational analysis of railway vehicles’ dynamics. The group’s main focus used to be on the development of software tools for the efficient analysis of general mechanical systems with a special emphasis on the dynamics of ground vehicles like automobiles, railway vehicles and aircraft landing gears. The respective research activ...
