OS1717 Evaluation of Dynamic Strength for Railway Passenger Seats

Abstract

In the event of a level crossing accident, train passengers sitting on seats have a risk of getting injured in collision with seats in front of them. In order to evaluate the passenger's injury quantitatively, we need to grasp physical properties of the seat in terms of dynamic strength. We carried out dynamic tests by striking seats with an impactor and FE analyses under the same condition as the tests. The numerical results obtained by FE analyses were generally consistent with the empirical results in terms of the load-time characteristics as well as the deformation of seats.
