Novel aluminum alloy roof for railway vehicle

Abstract

The invention discloses a novel aluminum alloy roof for a railway vehicle. The novel aluminum alloy roof comprises a dome assembly, an air conditioning unit platform, and a pantograph and pantograph-catenary detection platform. The air conditioning unit platform is located in the middle of the novel aluminum alloy roof and is used for mounting a single thin overhead two-end air outlet and two-endair return variable-frequency air conditioning unit. The pantograph and pantograph-catenary detection platform is located at the end of the novel aluminum alloy roof. The air conditioning unit platform is fixedly connected with an interface of the dome assembly by welding; and the pantograph and pantograph-catenary detection platform is fixedly connected with the interface of the dome assembly bywelding. According to the roof, vehicle body design efficiency is improved, a design risk is reduced, and then a reference basis is provided for realizing platformization, standardization and modularization of installing a single air conditioning unit roof on a B-type aluminum alloy vehicle body. In addition, the roof can be popularized and applied to subsequent similar aluminum alloy vehicle types, and a technical level of subsequent projects can be improved.

Description

Technical field: [0001] The invention belongs to the field of rail vehicle body design, in particular to a novel roof structure designed for rail vehicles. Background technique [0002] The invention is applied to the Hohhot Metro Line 1 project. According to Hohhot’s typical Mongolian plateau continental climate characteristics with obvious seasonal climate changes and large annual and daily temperature differences and user needs, it is targeted on the basis of summarizing the mature experience of existing vehicles. The development of a new single thin top-mounted air-conditioning unit with both ends of the air and both ends of the return air to ensure that the air-conditioning system is advanced, intelligent, reliable, comfortable, energy-saving, and environmentally friendly. The air volume distribution duct is set in the system to reduce noise and improve the uniformity of air supply. [0003] At present, the air-conditioning units with air outlet at both ends and return...

Problems solved by technology

[0006] In order to solve the problem that the parameters of the existing aluminum alloy roof cannot be used for reference and guide the design of the aluminum alloy roof of the Hohhot Metro Line 1 to install a single air conditioner, resulting in no corresponding aluminum material for the aluminum alloy roof of this new model For the technical problem of unifying the core structural parameters such as model selection and external dimension features, a new type of aluminum alloy roof for rail vehicles is designed, which is suitable for installing a single thin top-mounted air-conditioning unit with both ends of the wind and both ends of the return air. And through finite element analysis and static strength test, it is verified that the new aluminum alloy roof for rail vehicles meets the strength, fatigue and other performance requirements
