Lightweight door window for high-speed train

Technical Field

The utility model relates to a high-speed train is with lightweight door window belongs to the technical field of structure of product.

Background

The railway is used as a national economic aorta, a national important infrastructure and a popular vehicle, and has a very important position and function in the development of the national economic society. The planning proposes that a high-speed railway needs to be developed vigorously, a rapid railway network is basically built, and meanwhile, the modernization level of the locomotive vehicle equipment is continuously improved, which brings a rapid development history opportunity for the locomotive vehicle equipment of the high-speed railway in China. Therefore, high-speed trains, particularly trains with the speed per hour of more than 350Km, become mainstream equipment for future international and domestic railway development. Meanwhile, the improvement of the speed of the train also puts higher requirements on the fields of window structure design, material selection, manufacturing and the like. Taking a high-speed train with the speed per hour of 400Km as an example, the outer glass is required to resist 20g of gravel to impact at the speed of 220Km/h without being damaged, the weighted sound insulation quantity is required to be more than 45dB, and the heat transfer coefficient (K value) is required to be less than 1.2W/(m/h)²K) and also to meet the requirement for weight reduction (areal density of glass less than 40 kg/m)²). The glass weight of the existing high-speed train (the surface density of the glass is less than 47 kg/m)²) And the sound insulation and heat insulation properties do not satisfy the above requirements.
