摘　　要：传统的CNG汽车车辆碰撞安全性研究方法存在安全性差、抗碰撞性低等问题,为此提出一种CNG汽车车辆碰撞安全性研究方法。以相关碰撞安全标准和法规的分析为基础,分析了CNG汽车碰撞试验标准,将CNG汽车的结构特殊性与传统汽车的普适性相结合,构建了完整的试验模型。针对特殊的CNG高压系统结构设计了相应的碰撞安全试验,并对碰撞试验结果进行了对比研究。该方法可为增强中国CNG汽车行驶安全性提供有力参考。The traditional research methods for collision safety of CNG vehicles have problems such as poor safety and low collision resistance.Therefore,a research method for collision safety of CNG vehicles is proposed.Based on the analysis of relevant collision safety standards and regulations,the collision test standards for CNG vehicles are analyzed,and a complete test model is constructed by combining the structural specificity of CNG vehicles with the universality of traditional vehicles.Corresponding collision safety tests are designed for the special CNG high-pressure system structure,and the collision test results are compared and studied.This method can provide a strong reference for enhancing the driving safety of CNG vehicles in China.
