Embodiment 1

[0035] see figure 2 , image 3 with Figure 4 , a pantograph sinking platform cladding structure according to an embodiment of the present invention, the cladding structure mainly includes a top cladding plate 1, and the top cladding plate 1 covers the pantograph sinking platform on the top of the train 100, and the top surface cladding plate 1 has a streamlined transition with the roof of the train; the top surface cladding plate 1 partially covers the original pantograph sinking platform 100 on the top of the train, forming a pantograph 200 for accommodating The pantograph storage slot 2.

[0036] In the pantograph sinking platform cladding structure described above, the top cladding plate 1 is connected to the edge of the pantograph sinking platform 100 of the train, and the top cladding plate 1 is used to partially cover the original receiving plate on the top of the train. The pantograph is sunk into the platform 100 to form a pantograph storage slot 2, and the top cl...

Embodiment 2

[0047] see Figure 8 , a pantograph sinking platform cladding structure according to an embodiment of the present invention, the main structure of the pantograph sinking platform cladding structure is the same as that of Example 1, and the cladding structure is mainly different from that of Example 1 That is: the structure of the top surface cladding plate 1 is different from that of the first embodiment.

[0048] In Embodiment 1, the top surface cladding plate 1 remains flush with the car body on the top surface of the train; while in this embodiment, the top surface cladding plate 1 takes the form of a cladding plate convex, that is, the top surface cladding plate 1 The part close to the pantograph storage groove 2 protrudes upwards, and the protruding part has a streamlined transition with other parts of the top cladding plate 1. For its structure, see Figure 8 shown. The top surface cladding plate 1 is a convex cladding plate as a whole.

[0049] The cladding structure...

Abstract

The invention discloses a pantograph sinking platform coating structure which comprises a top surface coating plate, the top surface coating plate covers a pantograph sinking platform at the top of a train, and the top surface coating plate and the roof of the train are in streamline transition. The top surface coating plate partially wraps the pantograph sinking platform to form a pantograph containing groove used for containing a pantograph. For a vehicle model with a large sinking platform height, the top surface coating plate is flush with the vehicle roof, and an inclined cladding plate is arranged; and for a vehicle model with a small sinking platform height, the top surface coating plate adopts an outwards-protruding cladding plate which protrudes upwards, and no inclined cladding plate is arranged. According to the pantograph sinking platform coating structure, the aerodynamic resistance and aerodynamic noise of a pantograph system can be effectively reduced, and the aerodynamic performance of a pantograph area of a train is improved.

Description

technical field [0001] The invention relates to the technical field of railway transportation equipment, in particular to a pantograph sinking platform cladding structure. Background technique [0002] With the increase of train speed, the problems of aerodynamic resistance and aerodynamic noise are highlighted, which poses great challenges to train energy consumption and passenger comfort. The sharply increased resistance and noise have severely limited the speed-up of high-speed trains, and drag and noise reduction has become an inevitable requirement for the further development of high-speed trains in terms of speed-up, energy saving, and comfort. [0003] The train head car, tail car, bogie, car body connection and pantograph are important sources of train air resistance. The EMU composed of 8 CRH3 cars runs at a speed of 350km / h with open lines and no crosswinds. Under the operating conditions of the pantograph system, the aerodynamic resistance of the pantograph syste...
