A级标准二波波形梁护栏防护乘用轿车性能研究

Research on Protection Performance of Class A Standard Wave-shaped Beam Guardrail for Passenger Cars

为了解A级标准二波波形梁护栏对作为高速公路主流车型乘用轿车的防护性能,利用实车足尺碰撞试验验证其对乘用轿车的防护能力是否满足《公路护栏安全性能评价标准》(JTG B05-01—2013)(简称新标准)要求,并通过事故调研和分析,检验实际道路情况下对乘用轿车的防护能力。研究结果表明,A级标准二波波形梁护栏对乘用轿车的防护性能满足新标准要求,且在实际应用中性能表现良好。研究成果为A级标准二波波形梁护栏的合理应用提供了依据。

In order to understand the protection performances of Class A standard wave-shaped beam guardrail for the passenger cars as the mainstream vehicle model of expressway,the full-scale impact test with real vehicle is used to verify whether the protection performances of Class A standard wave-shaped beam guardrail for passenger cars to satisfy the requirements of Standard for Safety Performance Evaluation of Highway Guardrail(New Standard for short).Through the investigation,study and analysis on the accidents,the protection capacity of Class A standard wave-shaped beam guardrail is verified under the condition of the real roads.The study result shows that the protection performances of Class A standard wave-shaped beam guardrail for passenger cars satisfy the requirements of New Standard,and the performance is good in the practical application.The study achievement affirms the safety protection performance of Class A standard wave-shaped guardrail for passenger cars,which provides a basis for the rational application of Class A standard wave-shaped beam guardrail.
