Method for Evaluating Crashworthiness of Railway Vehicles Based on Correlation with Injury Severity of Passengers Occupying Longitudinal Seats

Abstract

Improving safety for train passengers in the event of a collision is a priority. To this end, this paper proposes safety indexes. The severity of injury for these indexes was estimated for a level crossing accident using numerical simulation. We compared the correlation between the severity of injury of a human model and the safety index of vehicles, which is the integral of deceleration waveforms, mean deceleration waveforms and maximum deceleration waveforms. It was found that the integral of deceleration values had the highest correlation with the injury values. We therefore propose using the integral of deceleration as a method for evaluating crashworthiness design.
