A级标准二波波形梁护栏防护乘用轿车性能研究

摘要:

为了解A级标准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A级标准波形梁护栏对乘用轿车的防护能力是否满足《新标准》要求，并通过事故调研和分析，检验实际道路情况下A级标准波形梁护栏对乘用轿车的防护能力。研究结果表明，A级标准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。研究成果肯定了A级标准波形梁护栏对乘用轿车的安全防护性能，为A级标准波形梁护栏的合理应用提供了依据。

Abstract:

In order to understand the protective performances of standard A-grade W-beam barriers for cars, which is the main composition of highway vehicle parts, full-scale impact test with real vehicle was used to verify whether the protective performances of standard A-grade W-beam barriers for cars satisfied the requirements of "new standard", and through investigating and analysing accidents, the protective performances of standard A-grade W-beam barriers for cars were inspected. The results of the study show that the protective performances of standard A-grade W-beam barriers for cars satisfy the requirements of "new standard", and the barriers perform well in the practical application. The achievement of the study make the performances of standard A-grade W-beam barriers for cars be approved and provides a basis for the rational use of standard A-grade W-beam barriers.
