碰撞假人头部性能指标HIC_(36)及HIC_(15)的区别研究

Study on the Difference Between Head Injury Criteria HIC_(36) and HIC_(15) of Crash Dummy

本文介绍了人体头部解剖学结构及HIC_(36)及HIC_(15)的选择,分析了头部损伤HIC及头部伤害限值变化。通过分析头部伤害发生的持续时间,得出当以HIC_(36)为考核指标时,不同的车辆出现最大伤害值的持续时间值可能并不相同,以HIC_(36)作为所有车辆的统一考核指标并不合适;而HIC_(15)伤害指标最大值出现在持续时间为15 ms时,对于不同的车辆,其考核指标进行了统一。对正面碰撞试验驾驶员、副驾驶员及侧面碰撞试验驾驶员的HIC_(36)及HIC_(15)数据进行了对比分析。结果表明:HIC_(36)修改为HIC_(15)可使不同车辆头部伤害评价标准更为统一,头部评价也更为严格。

The anatomical structure of human head and the selection of HIC_(36) and HIC_(15) were introduced.The head injury criteria(HIC)of head injury and the change of head injury limit were analyzed.Through analyzing the duration of head injury,it comes to a conclusion that when HIC_(36) is used as the evaluation index,the time duration of the maximum injury value of different vehicles may be different,so it is not appropriate to use HIC_(36) as the unified evaluation index of all vehicles.On the other hand,the maximum value of HIC_(15) injury index all occurs when the time duration is 15 ms,the assessment indexes are unified for different vehicles.The HIC_(36) and HIC_(15) data of frontal impact drivers,co-drivers and side impact tests driver were compared and analyzed.The results show that the modification of HIC_(36) to HIC_(15) can make the evaluation standard of head injury of different vehicles more unified and the evaluation of head injury more strict.
