Evaluation of Passenger Rail Vehicle Crashworthiness
In recent years there has been an increased effort to investigate and improve the crashworthiness of passenger rail vehicles in the United States. The structural crashworthiness requirements for new rail vehicles are changing to include specifications for crash energy management and crush zones rather than primarily specifications of vehicle and component strengths. In addition, the structural ...
متن کاملStructural Crashworthiness of Railway Vehicles
As a form of transport, rail has always maintained lower accident levels than its counterparts, the car and the airplane. The railway industry, however strives for still better safety measures to be implemented – a fact which intensifies with each accident that occurs. In the last years the continuous developments in technology, computer modeling capabilities and know-how have opened up various...
متن کاملSimulation and evaluation of urban rail transit network based on multi-agent approach
Purpose: Urban rail transit is a complex and dynamic system, which is difficult to be described in a global mathematical model for its scale and interaction. In order to analyze the spatial and temporal characteristics of passenger flow distribution and evaluate the effectiveness of transportation strategies, a new and comprehensive method depicted such dynamic system should be given. This stud...
متن کاملSimulation of Urban Rail Operations: Models and Applications
SimMETRO is a microscopic, dynamic, stochastic simulator of urban rail operations (METRO), specifically designed for service performance analysis, and evaluation of operations and strategies for real time control of subway systems. SimMETRO employs a detailed representation of the network, rolling stock, signal control, demand, schedule and dispatching. In particular, the various sources of sto...
متن کاملParallel and distributed crashworthiness simulation
This paper focusses on recent developments and on-going research related to parallel and distributed approaches for crashworthiness simulation, using the PAM-CRASH code from ESI as an example. The developments described here relate directly to the take-up in the automotive industry of the latest High Performance Computing (HPC) technology, since crash and safety analysis is well established in ...
