The invention relates to a low-noise pantograph area train body structure of a high-speed train. The low-noise pantograph area train body structure of the high-speed train comprises a train body aluminum profile, a fire-proof sound-insulation heat-insulation material and a train body interior trim panel. Through the research and optimization on a high-speed train pantograph and a surrounding flowfield structure of the high-speed train pantograph, a noise generation mechanism and a development rule of the noise generation mechanism, and drag reduction and noise reduction, important theoreticaland practical significance is realized in aspects of reducing the overall noise of the high-speed train, reducing noise pollution to the surrounding environment, reducing the energy consumption and improving the comfort of passengers. On the basis of deeply researching the structure of an existing motor train unit, a novel optimized structure is researched and developed in combination with the international advanced technology, and noise reduction, sound isolation, heat insulation and fire prevention system integrated innovative optimization design is mainly performed on a train body structure in a pantograph area.
