چکیده
|
In this paper,an investigation has been carried out to improve crashworthiness parameters of a passenger train using the dynamical simulation tool ls-dyna. tampons of a sample passenger train (iran dh4-1 paradise) in iran railway are modeled and the crashworthiness characteristic of it is improved by using the crashworthy element behind the set and also varying its shell material type. among most important collision scenarios mentioned in crashworthiness standards,the collision with heavy road vehicle at an intersection is considered. the simulation results obtained are validated by energy ratio and hourglass energy parameters.
