Universal-changing type vehicle end wall for testing rail vehicle end relation

Abstract

The invention relates to a universal-changing type vehicle end wall for testing the rail vehicle end relation. The universal-changing type vehicle end wall mainly comprises left and right large-folding-angle unit assemblies, left and right lengthening unit assemblies and a plurality of inner-outer side unit assemblies, wherein the left and right large-folding-angle unit assemblies are respectively and rotatably connected with adjacent two inner-outer side unit assemblies through hinges, the left lengthening unit assembly is respectively and rotatably connected with adjacent two inner-outer side unit assemblies through hinges, the installation position of one inner-outer side unit assembly is backward and parallel to the installation position of the other inner-outer side unit assembly on a vertical plane, and the right lengthening unit assembly is respectively and rotatably connected with adjacent two inner-outer side unit assemblies through hinges. The universal-changing type vehicle end wall can simulate vehicle end walls of any contours and dimensions. The vehicle end wall is excellent in universality, low in cost, and flexible and convenient for assembly. A simple and convenient universal-changing type simulation device is provided.

Description

technical field [0001] The invention relates to a car end wall used for the test of the car end relationship of a rail vehicle, in particular to an ever-changing car end wall which can simulate the car end walls of all rail vehicles. Background technique [0002] China's railways are in a period of vigorous development. With the sixth national railway speed increase in 2007, the Harmony CRH series EMUs appeared on Chinese railways for the first time, and achieved a high-speed operation of 250km / h on existing lines. It is the prelude to the development of high-speed railways. Since its development, the maximum speed of the EMUs in operation has reached 350km / h. However, with the increase of vehicle speed, the operating conditions of high-speed train vehicle ends and bogies become worse when the vehicle passes through the curve, and the safety and reliability problems of key components during operation become increasingly prominent. However, when the vehicle passes through th...

AI Technical Summary

Problems solved by technology

Since only one type of car end wall can be simulated, there are disadvantages of poor versatility and inconvenient adjustment

[0004] CN102128723A discloses a comprehensive test bench for car-end relationship, but no separate car-end wall is designed, and related tests are only carried out by adjusting the combination of different components installed at the car-end

Therefore, the outer dimension of the car end wall used in the existing car-end relationship test bench does not match the reality, and it is impossible to completely simulate the car end walls of all rail vehicles running on the actual line
