Modular multi-material crash-box for tailored impact energy absorption during low-speed collision (PROTECT)

低速（20英里/小时）事故同比增长31%（2016-2017年，运输部）;受伤人数的增长分为致命（+79%），严重（+47%）和轻微（+42%）。碰撞盒是附接在车辆保险杠结构和纵梁之间的薄壁结构，以改善低速事故中的碰撞性能。碰撞盒几何形状的确定对于吸收冲击能量是重要的，因为碰撞盒的安装空间不是很大。传统的碰撞盒（即由钢或铝制造的碰撞盒）表现出高峰值力，并且无法控制碰撞后的减速率。由于不可预测的故障，复合材料替代品的使用受到限制。PART是一种创新的新型碰撞盒，具有更好的冲击能量吸收能力，能够将对车辆本身、乘员和其他道路使用者的损害降至最低。在低速碰撞的情况下，PACT将有助于减少对车辆、乘客和公众的损害。这将导致更安全的道路和车辆，沿着以最小的维修成本。由于这一创新的解决方案，财团合作伙伴预计到2029年将创造227个就业岗位，并产生5160万英镑的累计收入。

Low-speed (20 mph) accidents saw year-on-year increase of 31% (2016-2017, Department of Transport); injury increase was broken down as fatal (+79%), serious (+47%), and slight (+42%). A crash box is a thin-walled structure attached between the vehicle bumper structure and the side rail to improve crash performance in low-speed accidents. The determination of the crash box geometry is important to absorb the impact energy, since the installation space of the crash box is not very large. Conventional crash boxes (i.e. those manufactured from steel or aluminium) exhibit high-peak force and have no way of controlling the rate of deceleration following a crash. Composite alternatives are limited in use due to unpredictable failure.PROTECT is an innovative new crash-box with better impact energy-absorption capabilities; enabling minimal damage to the vehicle itself, its occupants, and other road users. In the event of a low-speed collision, PROTECT will help reduce damage to the vehicle, its occupants and the wider public. This will result in safer roads and vehicles, along with minimised repair costs. As a result of this innovative solution, the consortium partners expect to create 227 jobs and generate cumulative revenues of £51.6 million by 2029\.
