摘要/Abstract

摘要： 碰撞安全是各种汽车在开发和生产过程中首先要面对的现实问题。由于压缩天然气（CNG）汽车存在高压管路和高压储气系统的结构特点，CNG汽车除了应满足传统汽车的碰撞安全要求外，还应满足相应的高压气体系统的安全要求；而在中国对于CNG汽车的碰撞尚无要求，在这方面的研究处于空白阶段。该文针对CNG汽车的结构特点和特性，研究和分析了国内外有关CNG汽车的碰撞安全法规及试验方法，探讨了国内CNG汽车碰撞安全的评价方法。分析了某车型的3种碰撞形态的4次碰撞试验结果，揭示CNG汽车在碰撞安全方面所存在的问题，提出了应采取的改进措施。该研究结果对于提高中国CNG汽车的碰撞安全性和制定中国的CNG汽车碰撞安全标准具有指导意义。

Abstract: Vehicle crash safety is the first question in automotive development and production process. As compressed natural gas (CNG) automobile has high pressure pipelines and high-pressured gas storage system feature, the CNG automobile should satisfy the traditional crash safety requirements, but also the requirements of corresponding compressed gas system. But there are not requirements regarding the CNG automobile collision standards in China, and it is also at blank in this aspect research. In view of the CNG automobile structure features and the characteristics, we have studied and analyzed related domestic and foreign CNG automobile collision safety rules and test methods and have established the domestic CNG automobile collision security appraisal system. Through the three kind collision modes of four impact tests result analysis to a certain kind vehicle, we have exposed the questions of CNG automobile which exist in the collision security aspect, as well as the improvement methods which we should adopt. It has guiding sense in enhancing CNG automobile safety in China and instituting CNG automobile collision security standard in China.
