Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] like figure 1 As shown, the head cover structure of the high-speed train head of the present invention is integrally cut into upper and lower parts, which are respectively an upper head cover 1 and a lower head cover 2 . Considering the overall shape of the train and the size of the doors, the dividing line 5 between the upper hood 1 and the lower hood 2 is set at the position of the dividing line between the car body 3 and the obstacle remover 4, and between the car body 3 and the obstacle remover 4. The dividing line 6 between them has a smooth transition.

[0025] For the convenience of installation and disassembly, it is installed outside the car body. The upper hood 1 and the lower hood 2 are plugged and connected to each other through a plug-in structure. The upper hood 1 is fixedly connected to the car body plate beams 7 located o...

Abstract

The invention relates to a hood structure of a high speed train headstock and an installation method. The hood structure consists of an upper hood and a lower hood, wherein the upper hood is connected with the lower hood through a plugging structure in a plugging manner, and the upper hood and the lower hood are respectively fixedly connected with a train body and / or train body accessory. The hood structure is simple in structure, the hood is divided into the upper hood and the lower hood, which are connected with each other in a plugging manner, the overall appearance effect is good, the entire structure is easy to install and disassemble, the upper hood and the lower hood can be placed into the train to run along the train after being disassembled, so that a link function and a rescuing function of the train can be realized. In addition, the hood can be installed externally, so that the problem that the hood cannot be installed due to the limited installation space inside the train body can be solved.

Description

technical field [0001] The invention relates to a head structure of a high-speed train, in particular to a head cover structure and an installation method of a high-speed train head, and belongs to the technical field of high-speed train car body manufacturing. Background technique [0002] As the running speed of the train continues to increase, the aerodynamic resistance experienced by the train also increases rapidly. In order to reduce the aerodynamic resistance and improve the aerodynamic performance, the overall shape of the front of the high-speed train adopts a streamlined shape, which helps to reduce air resistance. One of the important parameters of the front shape parameters is the slenderness ratio. When two high-speed trains meet each other, the higher the speed of the meeting, the greater the intensity of the pressure wave of the meeting. But the pressure wave of the meeting The amplitude will decrease significantly approximately linearly with the increase of t...
