Abstract

BACKGROUND

The World Health Organization has reported that 1.35 million people die on the roads every year due to road traffic accidents. This paper focuses on exploring a passive safety system that reduces lesions in the overtaking run-over scenario.

METHODS

Head Injury Criterion (HIC) and Combined Thoracic Index (CTI) were evaluated through numerical simulations using LS-Dyna®; in order to compare the computed results, three different speed scenarios were carried out (velocity of running over 40, 50, 60 km/h).

RESULTS

The computed results were divided into groups, A for the run-over test without a passive security system and B for the run-over test with a passive security system. For case A.1, the HIC15 was 3325. For case A.2, the HIC15 was 1510, and for case A.3, the HIC 15 was 1208. For case B.1, the HIC15 2605, for case B.2, the HIC15 was 1282, and for case B.3, the HIC was 730.

CONCLUSION

The comparative results show that the passive safety system installed on the bicycle has an increased benefit impact on the severity of the injury on vulnerable road users, decreasing the probability of cranioencephalic lesions in all study cases. In addition, the thorax injuries are cut down only in the impact scenario at a speed of 40 km/h.

摘要

背景

世界卫生组织报告称，每年有135万人死于道路交通事故。本文重点探讨一种被动安全系统，该系统可减少超车碾压场景中的损伤。

方法

使用LS-Dyna®通过数值模拟评估头部损伤标准（HIC）和胸部综合指数（CTI）；为了比较计算结果，进行了三种不同速度场景（碾压速度为40、50、60公里/小时）的模拟。

结果

计算结果分为两组，A组为无被动安全系统的碾压测试，B组为有被动安全系统的碾压测试。对于A.1案例，HIC15为3325。对于A.2案例，HIC15为1510，对于A.3案例，HIC15为1208。对于B.1案例，HIC15为2605，对于B.2案例，HIC15为1282，对于B.3案例，HIC为730。

结论

比较结果表明，安装在自行车上的被动安全系统对弱势道路使用者的伤害严重程度有更大的有益影响，在所有研究案例中降低了颅脑损伤的概率。此外，仅在40公里/小时速度的碰撞场景中胸部损伤有所减少。
