摘要:
 交通颅脑撞击损伤在交通事故中很常见,但由于旋转致伤实验装置复杂,旋转角加速度难于准确控制,因此颅脑旋转运动与颅脑损伤之间的关系及耐限还有待研究。针对上述技术瓶颈,本研究设计并构建了颅脑旋转碰撞实验平台。空载实验测试结果表明,气体输出压力为200 kPa时,角加速度峰值为(19 615.2±75.9) rad/s2;气体输出压力值为400 kPa时,角加速度峰值为(45 565.7±315.2) rad/s2。通过空载实验测试验证,该平台在不同输出气压时均能获得稳定可调节的角加速度。
Abstract:
 Craniocerebral injuries were common in traffic accidents. Due to the complexity of rotating-caused injury experimental device, the rotation angular acceleration is difficult to be controlled accurately. Therefore, the relationships between brain rotational motion and craniocerebral injury and the related tolerance limits have yet to be studied. To solve the above technique problems, we design and construct an experimental platform of craniocerebral rotating crash. With the air pressure of 200 kPa, the peak angular acceleration was (19 615.2±75.9) rad/s2; with the air pressure of 400 kPa, the peak angular acceleration was (45 565.7±315.2) rad/s2. Through no-load experiment, this device was proved to be able to control the angular acceleration precisely under different air pressures.
