Abstract

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.

Key words: compressed natural gas (CNG) , vehicle, safety assessment, crash test
