Problems solved by technology

However, the current common single-piece structure of the existing EMU car body has an energy-absorbing function to a certain extent, but it does not involve a whole-vehicle front structure that can provide high-strength and rigid support for energy-absorbing components.
Secondly, the main energy consumption during the high-speed operation of the train is caused by aerodynamic resistance. The front of the existing rail vehicle can not well reduce the air resistance when the train is running, and reduce the train drag coefficient.

Abstract

The invention discloses a vehicle head structure of a railway vehicle. The vehicle head structure is in a shuttle shape as a whole. Pneumatic flow guide ridges are symmetrically arranged on the two sides of the middle of the vehicle head structure. The pneumatic flow guide ridges on the same side are each provided with a pneumatic flow guide groove. Each pneumatic flow guide groove is of a front-low and back-high structure. The vehicle head structure has the advantages that aluminum alloy serves as the base material for the whole vehicle head structure, an aluminum alloy panel is connected with a profile through welding, and the collision strength, light-weight performance and air dynamics performance of the vehicle head structure can be improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a locomotive structure of a rail vehicle. Background technique [0002] With the development of high-speed rail technology, the performance requirements for the constitutive safety of high-speed rail are getting higher and higher, so there is an urgent need for a car body structure that can meet the constitutive safety of high-speed rail, and can effectively ensure the safety of drivers and passengers when trains collide with each other. Safe space, and the driver's cab is equipped with an escape window, which can achieve the purpose of rapid escape of personnel. However, the current common single-piece structure of the existing EMU car body has an energy-absorbing function to a certain extent, but it does not involve a whole vehicle front structure that can provide high-strength and rigid support for energy-absorbing components. Secondly, the main energy consumption durin...
