摘要
在新版中国新车评价规程(C-NCAP)评价指标中,正面碰撞试验中后排女性假人胸部是失分重点部位,胸部伤害的影响因素是当前被动安全研究的重点之一。该文在约束系统开发过程中进行了12次50 km/h实车正面碰撞试验,用与前排50%男性假人对比方法,研究了后排女性假人胸骨刚度、安全带作用效果、安全带作用时机、及假人相对运动。结果表明:在普通安全带作用下,女性假人胸部刚度低于男性假人胸部刚度,约为一半;5%女性假人配带50%男性假人安全带,有效作用起步时间比男性假人偏晚,迟约30 ms,且后期形成急速拦截冲击,这些因素导致了后排女性假人胸部伤害普遍较高。因而,较高的车体前端刚度,比较有利于后排女性假人胸部的保护。
The rear-row female chest is the emphases lost score position in the frontal impacting test in the new China New Car Assessment Program （C-NCAP）. The research of female chest injury influencing factors is passive safety emphases. The authors investigated the sternum rigidity for 5% male dummy, the seat belt action effect, the seat belt action time, the dummy relative move using a contrast method between a rear-row female dummy and a front-row 50% male dummy in twelve frontal impacting tests at 50 km/h. The results show that female dummy sternum rigidity islower than male, about half of it, when using a general seat belt, and that the effective action start time is about 30 mslater than male, and a sudden-hold impacting occurred in the impact end stage; and that the chest injury severity of the rear-row female dummy in impaction with using seat belt by a 5% female dummy is designed for 50% male dummy. Therefore, a higher rigidity of vehicle front part can make a better protection for female dummy chest.
