摘要： 开发了一种用于约束系统（即气囊和安全带）优化设计的前碰Sled 数值模型。该模型包括驾驶员侧边座舱
和老年人体模型。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。束缚系统的设计变量有3 种：安全带负载极限的峰值受力、安全带预张
或气囊的展开时间、和喷气孔的直径。结果表明：减少在汽车发生前碰时胸部伤害的风险，相比于年轻乘员, 老年驾
驶员需要更低的安全带预张或气囊的限制负载力。

Abstract:  A numerical frontal impact sled model was constructed and simulated consisted of driver side cockpit and elderly
human body for an optimal design of restraint system, i.e., air bag and seat belt. 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. There were three design variables for the restraint, i.e., peak force of belt load limiter, deployment time of belt
pretensioner/airbag, and the vent hole size. The results show that the smaller size of vent hole, earlier firing of belt pretensioner/
airbag and lower belt limit load are needed to reduce the chest injury risk of elder driver in a front crash by comparing with the
restraint design for the younger population.

Key words: automotive safety, frontal impact, restraint system, chest injury risk, elder driver
