挡风玻璃作为司机与外界交流的一个接口,在动车组的运行中,不仅是司机了解外界环境信息的关键部件,对列车的正常运营起重要作用,挡风玻璃的设计除了要满足与车体的接口要求,还要满足自身的力学、光学、耐候性、电性能、热学性能等要求。本文从挡风玻璃的接口设计和本身应满足的性能要求两方面进行阐述。 Windshield, as an interface between drivers and the outside world, is not only a key component for drivers to understand environmental information in the operation of EMUs, but also plays an important role in the normal operation of trains. The design of the windshield should meet the requirements of the vehicle body Interface requirements, but also to meet their own mechanics, optics, weatherability, electrical properties, thermal properties and other requirements. This paper elaborates on the interface design of the windshield and the performance requirements that should be met by itself.
