【摘要】：铁路运输系统作为人们日常生活中必备的交通运输工具,其发展迅速,自第六次全国铁路大提速以来,我国铁路逐步进入高铁时代。随着列车运行速度的不断提升,列车在生产制造过程中,大量易燃非金属复合材料被应用其中,复合材料的易燃性、有毒性给列车带来了严重的火灾安全隐患,对列车的行车安全构成极大的威胁。因此,对高速列车的防火性能进行研究显得异常重要。我国对轨道车辆的防火研究工作起步晚,且大多采用理论及仿真分析的方式,虽然各相关部门及研究机构制定了一些相关的标准与规范,但这些标准大多参照甚至直接引用国外标准,各国的防火标准无论是在试验方法还是性能指标上差异性都较大,对我国高速列车的防火安全要求适用性有待验证。因此本文通过梳理世界各国轨道车辆防火标准,并针对目前国际上最为常用的轨道车辆材料、部件及结构防火测试标准DIN5510-2、BS6853、EN45545-3对我国某型号高速列车常用非金属材料、客室及司机室座椅、8种电线电缆、22种电气设备关键零部件以及厨房配电柜和保温箱进行相关的防火性能测试。根据各测试结果评判了各种材料、部件及结构的防火性能,且通过试验过程中对各标准试验内容、试验方法以及评价指标的进一步分析及对比,结合试验过程中观测到的一些试验现象及对同一材料的不同试验标准的结果对比,指出国外标准对于我国高速列车防火性能适用性上存在的不足,并对我国高速列车防火标准的建立提出建议。另外,文中大量的燃烧试验在国内研究实数先例,为今后建立我国高速列车防火标准体系提供了重要的参考依据。
[Abstract]:The railway transportation system, as a necessary means of transportation in people's daily life, has developed rapidly. Since the sixth national railway increased speed, China's railway has gradually entered the era of high-speed rail. In the manufacturing process of trains, a large number of combustible nonmetallic composites are used. The flammability and toxicity of the composites bring serious fire safety risks to the trains, and pose a great threat to the train safety. It is very important to study the anti-fire performance of high-speed train. The research work on anti-fire of rail vehicles in our country started late, and most of them adopt the methods of theory and simulation analysis, although the relevant departments and research institutions have formulated some relevant standards and norms. However, most of these standards refer to or even directly refer to foreign standards, and the fire prevention standards of various countries differ greatly in terms of test methods and performance indicators. The applicability of fire safety requirements for high-speed trains in China needs to be verified. Therefore, through combing the fire prevention standards of rail vehicles in the world, and aiming at the most commonly used rail vehicle materials in the world at present, The fire resistance test standard DIN5510-2 BS6853N45545-3 for components and structures is commonly used as non-metallic materials for a certain type of high-speed train in China. Eight kinds of electrical equipment, 22 kinds of electrical equipment, and kitchen distribution cabinets and heat preservation boxes are tested for fire resistance performance of various materials, components and structures according to the test results, and the fire resistance of all kinds of materials, components and structures are evaluated according to the results of the tests, and the fire resistance of all kinds of materials, components and structures are evaluated according to the test results. Through the further analysis and comparison of each standard test content, test method and evaluation index, combined with some experimental phenomena observed in the course of the test and the results of different test standards for the same material, It is pointed out that the foreign standards are inadequate for the applicability of fire prevention performance of high speed trains in China, and some suggestions are put forward for the establishment of fire prevention standards for high speed trains in China. In addition, a large number of combustion tests in this paper have been studied in China with practical precedents. It provides an important reference for the establishment of fire-proof standard system of high-speed trains in China in the future.
