With the increasing speed of railway vehicles, deciding how to reasonably distribute impact
energy to each vehicle has been a widespread concern in safety protection systems. This …

Optimization for the energy-absorbing structures can achieve their better crashworthiness
and lightweight performance. However, traditional optimization methods cannot handle …

In this study, a new cut-out groove design is addressed, aiming to improve the
crashworthiness of a gradual energy-absorbing structure for subway vehicles. First, the …

The collision performance of crashworthy structures can be improved using the optimization
design. However, conflicting objective functions and the non-uniqueness of solutions hinder …

The optimization of the crashworthiness and lightweight design of S-rail extracted from the
frontal body in white was studied in this paper. A physical test was conducted to verify the …

By coupling thin-walled metal and aluminium honeycomb structures, a composite energy-
absorbing structure with a high strength to weight ratio was designed. The validity of …

In this paper, we proposed a strategy to improve the energy absorption efficiency of a square
multi-cell tube by designing the lateral wall thickness distribution. We uniformly arranged the …

This paper presents an investigation of the crashworthiness of expanding circular tube
energy absorbers with a cylindrical anti-clamber under eccentric loading for subway …

Traditional finite element (FE) methods are arguably expensive in computation/simulation of
the train crash. High computational cost limits their direct applications in investigating …

Energy-absorbing structures with anti-climbers for railway vehicles rarely experience pure
axial loading in real crash events, but rather a combination of axial and off-axial loads. In this …
