Abstract

Recent interest by automotive manufacturing company is to develop a component, capable of enhancing safety features associated with lightweight materials such as using aluminum and composites. The use of aluminum metal matrix composites (MMC) and composite materials improve the performance of an automotive crash box due to their lightweight. Automotive crash box is a component, equipped at the front end of a car, and is one of the most important devices for crash energy absorption. The review is mainly divided by two topics, i.e. design of geometry profiles and the crash box material advancements, both geometry and material properties would influence the efficiency of kinetic energy absorption during collision. This review benefits both academics and corporate sector as it outlines major lines of research in the crash box design. It discusses the results from 3D simulations up to laboratory experiments of crash box specimen and the effect of material selection to the characteristic of crash box device. The information from this paper should stimulate more research and more crash box design solutions to reduce fatal damage during collision in automotive industry.

汽车碰撞箱设计与材料开发综述

汽车制造公司最近的兴趣是开发一种部件，能够增强与轻质材料(如使用铝和复合材料)相关的安全特性。铝金属基复合材料(MMC)和复合材料的使用由于其轻量化而提高了汽车碰撞箱的性能。汽车碰撞箱是安装在汽车前端的部件，是吸收碰撞能量的重要装置之一。综述主要分为两个主题，即几何轮廓的设计和碰撞箱材料的进展，几何和材料的性能都会影响碰撞时的动能吸收效率。这篇综述对学术界和企业界都有好处，因为它概述了碰撞箱设计的主要研究方向。讨论了从三维模拟到室内试验的碰撞箱试样的结果，以及材料选择对碰撞箱装置特性的影响。本文所提供的信息应该激发更多的研究和更多的碰撞箱设计解决方案，以减少汽车工业碰撞中的致命伤害。
