Dynamic Analysis of High Speed Rail-Vehicle Collisions
In the event of a collision between a traveling, high speed train and a vehicle, the scale of human fatality and property damage can increase substantially if the train derails from its track after impact. Hence, it is important to identify the conditions and factors that may potentially lead to derailment in the event of a train-vehicle collision incident at a highway rail grade crossing. This...
متن کاملComputation of Slip analysis to detect adhesion for protection of rail vehicle and derailment
Adhesion level for the proper running of rail wheelset on track has remained a significant problem for researchers in detecting slippage to avoid accidents. In this paper, the slippage of rail wheels has been observed applying forward and lateral motions to slip velocity and torsion motion. The longitudinal and lateral forces behavior is watched with respect to traction force to note correlatio...
متن کاملCrashworthiness Analysis and Energy Absorption Enhancement of a Passenger Rail Vehicle
Interests in increasing the trains’ speed of travel, generated higher degrees of wariness about the possible sever accidents. Since, the passenger wagon car body needs to be a safe compartment for its occupants therefore; great attention should be paid on its design. In this study, a passenger car body that is originally made in Eastern Germany and its chassis are modeled to simulat...
متن کاملEvaluation 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 کاملMultiobjective robust design optimization of rail vehicle
This work deals with the multiobjective robust design optimization of rail vehicle systems moving in short radius curved tracks. Two criteria are considered simultaneously, i.e., safety and comfort. We showed that the deterministic optimal solutions, for the nominal design parameters, can be altered seriously by the design parameters uncertainty. A new algorithm that combines Genetic Algorithms...
