摘要

以suv为研究对象，开发具有中国特色的侧面变形屏障。通过提取典型suv的特征参数，确定了蜂窝铝护栏和小车的发展目标，并应用理论分析指导了护栏材料的选择。基于护栏小车的动态荷载箱壁试验，提出了蜂窝铝标定性能的评价方法。通过车对车碰撞试验，形成了一种基于车身结构变形和碰撞载荷力高度分布的验证方法。结果表明，新型移动变形屏障的力学性能满足设计要求，原型在变形模式下稳定，能够表征SUV的外观和刚度特性。

Performance design, development and verification of honeycomb aluminium barrier for vehicle side impact

SUVs are taken as the research object to develop the side deformation barrier with Chinese characteristics. By extracting characteristic parameters of typical SUVs, honeycomb aluminium barrier and trolley development objectives are defined and theoretical analysis are applied to guide the selection of barrier materials. Based on the dynamic load-cell wall test of barrier trolley, the evaluation method of honeycomb aluminium calibration performance is proposed. Through car-to-car crash test, a new verification method based on the deformation of the body structure and the height distribution of the crash load force is formatted. The results show that the new moving deformation barrier’s mechanical properties meet the design specifications, the prototype is stable in deformation modes and it can characterise the appearance and stiffness characteristics of SUV.

期刊介绍： International Journal of Crashworthiness is the only journal covering all matters relating to the crashworthiness of road vehicles (including cars, trucks, buses and motorcycles), rail vehicles, air and spacecraft, ships and submarines, and on- and off-shore installations. The Journal provides a unique forum for the publication of original research and applied studies relevant to an audience of academics, designers and practicing engineers. International Journal of Crashworthiness publishes both original research papers (full papers and short communications) and state-of-the-art reviews. International Journal of Crashworthiness welcomes papers that address the quality of response of materials, body structures and energy-absorbing systems that are subjected to sudden dynamic loading, papers focused on new crashworthy structures, new concepts in restraint systems and realistic accident reconstruction.
