train, this paper presents the energy absorption design study for CEM passenger trains …

A three-dimensional numerical finite element model was established by Abaqus to study the
time-history curves of train-to-tunnel impact forces for impacts at different velocities, train …

As part of an ongoing passenger rail crashworthiness effort, a full-scale impact test of a train
with crash energy management (CEM) passenger cars was conducted on March 23, 2006 …

A large number of numerical simulations are required to design an energy absorption
scheme for train crashworthiness, leading to low design efficiency in the early stage. Based …

The dynamic response of distributed energy absorption system used as a passive safety
device in high-speed trains is investigated with a one-dimensional wave propagation model …

Abstract Crash Energy Management (CEM) is a crashworthiness strategy that incorporates
crush zones into the design of passenger railcars. In the event of a collision, crush zones are …

In the current paper, the authors present an analysis of the structural characteristics of an
intermediate rail vehicle and their effects on crash performance of the vehicle. Theirs is a …
