The objective function in the optimization process was to minimize the chest injury risk while keeping the other injury risks ( i.e., head injury criterion ( HIC ) and femur load ) under the thresholds. 最佳化过程的目标函数是,在保持其他伤害风险(例如,头部伤害标准(HIC)和股骨负荷)低于阈值的前提下,使得胸部伤害的风险为最小。
Dynamic and kinematics data were obtained, and severity index ( SI ), head injury criterion ( HIC ) and dynamic response index ( DRI ) were derived. 测得不同弹射加速度作用下的动力学和运动学数据,并计算了严重指数、头损伤指数和动态响应指数。
The numerical results of head injury criterion and leg injury criterion show that train crashworthiness and secondary collisions are the key reasons to result in passenger injury. 假人模型中的有关头部伤害指标和大腿伤害指标的计算结果表明,列车碰撞及其乘员二次碰撞是导致乘客伤害的关键原因。
