Passive and active energy dissipation devices for superior crashworthiness performance

拟议的研究计划将继续进行实验，数值和理论研究，以开发新型和高性能的结构能量吸收装置。这些调查将寻求了解和开发与许多安全应用相关的被动和主动自适应能量耗散结构，包括但不限于个人安全设备和汽车，航空航天和防爆行业。 两个具体的研究领域是针对这些自适应的能量耗散装置的发展，即，（i）的应用切割变形模式的挤压实现一个系统，表现出所需的和控制的负载/位移行为在变形过程中，和（ii）泡沫填充编织管作为一种新型的能量耗散装置的理解和发展。 该研究项目的长期目标是开发高性能、新颖、坚固和有效的能量吸收装置，以减轻在广泛的安全应用中由于福尔斯坠落、汽车碰撞、行人碰撞、爆炸或炸弹爆炸造成的严重伤害或死亡。

The proposed research program will continue experimental, numerical, and theoretical studies towards the development of novel and high performing structural energy absorbing devices. These investigations will seek to understand and develop both passive and active adaptive energy dissipation structures relevant to many safety applications, including but not limited to, personal safety devices and automotive, aerospace, and blast protection industries. Two specific areas of research are targeted towards the development of these adaptive energy dissipation devices, namely, (i) the application of a cutting deformation mode of extrusions towards achieving a system which exhibits desired and controlled load/displacement behaviour during deformation, and (ii) the understanding and development of foam filled braided tubes as a novel energy dissipation device. The long term objectives of this research project are to develop high performance, novel, robust, and effective energy absorbing devices so as to mitigate serious injuries or death as a result of falls, automotive crashes, pedestrian impacts, blasts, or bomb explosions in a broad range of safety applications.
