Locomotive structure of high-speed train

Abstract

The invention relates to a locomotive structure of a high speed train. A locomotive has streamline appearance; a head of the locomotive is a rotating body nose cone; a plow-shaped spoiler is arranged below the nose cone; a diversion trench structure is formed by the spoiler and the nose cone; the nose cone is connected with a wedge-shaped cab; the upper part of the cab protrudes upward to form an ellipsoidal vehicle front window; the nose cone, the cab and the vehicle front window are in smooth transition; and the height h from the center line of the nose cone to the bottom of the locomotive is 1 / 4 to 1 / 3 of the total height H of the locomotive. According to the invention, the nose cone at the head of the locomotive is a rotating body, so that the locomotive structure is beneficial for reducing the air resistance; by the reasonable matching of the diversion trench, the locomotive structure is beneficial for guiding most of air flow to the upper part of a vehicle body and both sides of the vehicle body and most of air flow is avoided entering a gap at the lower part of the vehicle body and a bogie region, and thus, the air resistance is effectively reduced; and due to the arrangement of the ellipsoidal vehicle front window, not only can the aerodynamic noise at the position be reduced, but also a visual field of a driver and the inner space of the cab can be increased.

Description

technical field [0001] The invention relates to a locomotive structure of a high-speed train, in particular to a locomotive structure of a high-speed train whose running speed is above 380 km / h, and belongs to the technical field of high-speed train body manufacture. Background technique [0002] As the speed of the train continues to increase, the aerodynamic resistance suffered by the train also increases rapidly. At the same time, during the high-speed operation of the train, the high-speed train interacts with the ground, surrounding facilities, and other trains running on the line, forming a complex Fluid-solid coupling effect: The aerodynamic lift force, crossing lateral force and crosswind effect on the train will adversely affect the stability of the train; the surface pressure of the train and the crossing pressure wave will have a negative impact on the strength of the car body; Aerodynamic noise will have adverse effects on ride comfort and the surrounding environ...
