Chassis equipment cabin baseplate for high-speed rail vehicle

Abstract

The invention provides a chassis equipment cabin baseplate for a high-speed rail vehicle. The chassis equipment cabin baseplate comprises an outer skin, an inner skin, a middle foam interlayer and a hook, wherein both the outer skin and the inner skin are made of carbon fiber twill fabric and carbon fiber unidirectional fabric and adopt the vacuum injection formation technology; the middle foam interlayer is made of PVC interlayer foam and adopts the vacuum injection formation technology; the PVC interlayer foam comprises a foam body part and an edge part on the edge of the foam body part; the hook is arranged at the common end parts of the outer skin, the inner skin and the middle foam interlayer. The production method of the chassis equipment cabin baseplate is easy to operate, and short in production time; as the outer skin and the inner skin, which are made of carbon fiber composite materials, as well as the middle foam interlayer adopt the vacuum injection formation technology, the chassis equipment cabin baseplate has the advantages that the surface is smooth and flat, the assembly parts are less, the assembly cost as well as the assembly time is greatly reduced, and routine maintenance is easy.

Description

technical field [0001] The invention relates to a high-speed bullet train composite bottom equipment cabin bottom plate. Background technique [0002] With the rapid increase in the operation speed of domestic trunk railways and urban light rail, higher design standards have been put forward for vehicle lightweight and safe operation performance. The undercarriage beam place of existing rail vehicle is generally provided with equipment cabin, to set up wire groove, wire pipe and most of the undercarriage equipment in other trains inside the closed space of equipment cabin. When the train runs at high speed, it will generate a strong air pressure wave, so that small stones, ice cubes or other objects near the bottom of the train and the track will be sucked up, and these objects will hit the equipment installed under the train, endangering The safety of train operation, especially for high-speed EMU trains, this hazard will be greater. [0003] At present, in order to prote...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a light-weight high-strength composite vehicle bottom equipment cabin floor to solve the problem of existing equipment cabin floor with heavy weight, complex load conditions, easy panel degumming, and severe temperature changes. There will be a lot of thermal stress on the inner side, which will cause the problem of debonding of the bottom plate of the equipment compartment
