Assessment criteria for assessing energy-absorbing front underrun protection on trucks

Vehicle Front Structure Energy Absorbing Optimization in Frontal Impact

Energy absorption performance is one of the most important indexes in the vehicle safety during impact. Research on the car frontal structure energy performance and structure optimization was conducted in this paper. Whole vehicle model was established by HyperMesh and simulated in LS-DYNA. Simulation results indicated that modification was need for the original structure to meet requirement. B...

The application of energy-absorbing structures on side impact protection systems

This paper presents a system to improve the protection to the occupants of a World Rally Championship Car in case of a side impact involving a tree collision using energy absorbing structures. An outline of the immediate events after the car crash into a tree are provided followed by an analysis of a typical standard rollcage, then the design criteria and features of a carefully selected design...

Criteria Assessment of Energy Carrier Systems Sustainability

Assessment and Design Enhancement of the Front End Energy Absorption Mechanism of a Locomotive Based on an Impact Scenario

This research is concerned with weighing the behavior of the front end energy absorption system of a locally manufactured locomotive in crash situations. The causes of the extensive damages to the energy absorption apparatus that includes the crash element and the buffer are studied. By choosing the proper damage model the conditions of the accident is simulated by using the ABAQUS engineering ...

3d Woven Composites for Energy Absorbing Applications

Due to the presence of through-thickness reinforcement, 3D woven composites have superior fracture toughness, fatigue life, and damage tolerance compared to laminated composites. Furthermore, 3D woven composites exhibit a progressive damage behavior which is more benign than the typical catastrophic failure behavior of laminated composites. These properties lead to high specific energy absorpti...
