Guo Shuwen Lu Shen Gu Haiming Li Xiaodong

Abstract：With the rapid development of Chinas economy， Chinas automobile industry has also undergone earth-shaking changes. The number of cars in China is increasing， and the forms of road traffic in China have become increasingly complex， making automobile consumers more than just buying a car. Its just a means of transportation. When choosing a car and buying a car， it pays more and more attention to the safety performance of the vehicle; automobile companies also put the development of vehicle safety performance in a crucial position， and increase various research and development methods and technical capabilities. The reserves and investment in China have promoted the continuous progress of China's automotive safety technology， and the safety performance of vehicles has also been continuously improved. This article mainly studies the water tank frame at the front of the vehicle， and studies its influence on the safety performance of the vehicle to guide the development of the passive safety performance of the vehicle.

Key words：passive safety， frontal collision， water tank frame， safety regulations

1 引言

中國汽车车辆的保有量随着中国经济的发展在持续攀升，目前全国汽车保有量大约为2.8亿辆左右[1]，每年销售整车已经达到2800万辆左右。伴随车辆数量的增加，带来的车辆安全问题日趋复杂。道路使用者较以前更加复杂，各种机动车、非机动车、行人等穿插于道路之中，每年的安全事故形态日益繁杂。因此不论消费者还是主机厂均把车辆安全性能看得日益重要，为提高车辆安全性能主机厂进行更多的人力和物力的投入。

经过多年的发展，车辆被动安全已经形成较完善的评价体系，从标准性质划分主要分为强制性标准和非强制性标准以及NCAP体系，国内强制性标准主要包括GB11551-2014《汽车正面碰撞的……
