Kinetic energy dissipation system to reduce and control impact forces

提出的技术是由切割构件和牺牲变形管组成的动能消能系统。在撞击时，该装置的形状像一个带有四个辐条状刀片的钢轮，切割通过牺牲变形管，使金属除了被切割外还能拉伸，而不是不均匀地起皱。该技术被设计成仅允许预定大小的力通过系统传递到接收体。这种一次性使用的装置能够消散高水平的能量，包括来自爆炸装置的能量。该装置的目的是将到达接收体（例如车辆中的人类乘员）的能量限制在一定水平，使得他们不会因撞击而受到严重伤害。技术设计的简单性使其能够容易且廉价地制造。 实验结果表明，在测试中采用不同的轴向载荷（范围从缓慢移动的车辆碰撞的等效炸药）和不同的速度，所提出的技术可以有效地消散各种冲击力的动能，具有非常相似的结果。 旨在尽量减少高能量冲击力影响的技术有可能减少严重和危及生命的伤害，主要适用于车辆事故和军事爆炸的情况。每年约有17万加拿大人在汽车事故中受伤，2014年有超过2000人死亡。汽车行业将安全性放在首位;先进的车辆安全性不再仅限于高级车辆，现在通常安装在入门级车辆上。在全球范围内，汽车安全系统市场规模庞大，2013年达到243亿美元。所提出的技术可用于消散和/或吸收设定量的能量，该能量可被并入汽车、军用车辆、防撞护栏或其他结构中以消散震动或冲击力的动能。这种新型的能量耗散系统有可能在高能量冲击的情况下减少严重伤害并挽救生命。

The proposed technology is a kinetic energy dissipation system composed of a cutting member and a sacrificial deformation tube. Upon impact, the device, shaped like a steel wheel with four spoke-like blades, cuts through the sacrificial deformation tube causing the metal to stretch in addition to being cut, rather than crumple unevenly. This technology is designed to allow only a predetermined magnitude of force to be transmitted through the system to the receiving body. This one-time use device is capable of dissipating high levels of energy including those from explosive devices. The intent of the device is to limit the energy to the receiving body (for example human occupants in a vehicle) to a level so that they would not be severely injured by the impact. The simplicity of the technology design enables it to be easily and inexpensively manufactured. Experimental results revealed that in tests employing the use of different axial loads (ranging from the equivalency of slow-moving vehicle collisions to explosives) and different velocities, the proposed technology can effectively dissipate the kinetic energy of various impact forces with very similar results. Technologies designed to minimize the impact of high energy shock forces have the potential to reduce critical and life-threatening injuries, mainly applicable in instances of vehicle accidents and military explosions. Each year approximately 170 000 Canadians are injured in automobile accidents, with over 2000 reported fatalities in 2014. The automotive industry has responded by putting safety at the forefront; advanced vehicle safety is no longer restricted to premium vehicles and is now commonly installed in entry level vehicles. On a global scale, the automotive safety system market is expansive, encompassing 24.3 billion USD in 2013. The proposed technology can be used to dissipate and/or absorb a set amount of energy that can be incorporated into an automobile, a military vehicle, a crash barrier, or other structures to dissipate the kinetic energy of a shock or impact force. This novel energy dissipation system has the potential to reduce critical injuries and save lives in instances of high energy impact.
