摘要： 中国乘用汽车第二排乘坐率高，对乘客员的保护力度不够。该文参考09 版中国新车评价规程
（C-NCAP）中的相关规则，研究了评价第二排乘员伤害的100％正面碰撞的试验方法和基于生物力学限值
指标的定量评分方法。对新近上市29 款车型进行试验。结果表明：第二排乘员颈部遭受致命伤害的
17 款，占59％；胸部遭受致命伤害的10 款，占35％。对第二排座椅上混合Ⅲ型第5％百分位的女性
假人动力学响应的分析结果表明：安全带肩带力与颈部拉伸力、胸部压缩量之间呈近似线性关系。安
全带肩带是造成假人上躯干伤害的主要原因。因此，为有效降低这种伤害，应优化、调整普通安全带
参数。

Abstract: The second seat row has a high riding rate but a low rider protection level in vehicles running in
China. This paper investigates test methods based on the 100% frontal impact test rule of 2009 version of China
New Car Assessment Program (C-NCAP), and presents a quantitative evaluation method for the biomechanics
limit value of the second row passengers. Tests in vehicle 100% frontal impacts for 29 types of vehicles recently
coming into China’s market showed that the second row occupants suffered fatal neck injury in 17 types of the
vehicles (58.6% of total vehicle samples) and fatal chest injury in 10 types of vehicles (34.5% of total vehicle
samples). The analyses show that the seat belt shoulder strap, neck tension force, and chest compression
displacement have an approximately linear relationship in the dynamics response characteristics of mixed III
type, the 5th percentile, female dummies in the second row seats. The results indicate that the occupant upper
body injury is mainly caused by the safety belt shoulder strap. Therefore, parameter optimization and adjustment
are necessary for common safety belts to effectively reduce the harm.

Key words: vehicle safety, 100% frontal crash test, the second row female dummy, evaluation method, dynamics response
