A Special Collaborative Information System and Its Application in Kinetic Energy Impact

Although the benefits of the non-lethal kinetic energy projectiles are numerous, there is a need to assess the projectiles to assure their expected functions. In order to overcome the limitations of current research, a special collaborative information system based on Hybrid III 50th percentile male dummy (hybrid III dummy) was developed and validated to assess and predict the risk of non-lethal kinetic energy impact. Two types of non-lethal kinetic energy projectiles were used to attack the thorax region of the dummy surrogate at six levels of distance. Not only the sensors inside the dummy as a mechanics information system recorded all the kinetic energy impact measures accurately and effectively, but also other systems like acquiring and processing information system including hardware and software played their roles respectively. The acceleration response, displacement response showed consistent patterns with the kinetic energy measures. The results showed that the measurement from the special system was reliable for non-lethal kinetic energy projectiles. The maxima of displacement, viscous criterion (VC) and kinetic energy were both lower than correlative injury thresholds. Current study provided an alternative method to assess the performance of the non-lethal kinetic energy projectiles.
