Abstract

The invention provides a railway vehicle equipment compartment bottom plate and a railway vehicle equipment compartment bottom plate framework, and the railway vehicle equipment compartment bottom plate comprises a first skin, a second skin and a foam structure layer; the first skin and the second skin are made of glass fiber reinforced plastic materials; and a foam structure layer is filled between the first skin and the second skin. The railway vehicle equipment compartment bottom plate and the railway vehicle equipment compartment bottom plate framework provided by the embodiment of the invention accord with high-quality and high-requirement regulations of intelligence, environmental protection, sustainable development and the like, even if high-tech equipment on a vehicle is increased, the weight of a vehicle body can be reduced through the bottom plate and the equipment compartment damping cross beam which are made of glass materials, and the weight of the vehicle body is reduced. And the impact of splashing foreign matters on the rail surface can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of composite panels, in particular, to a rail vehicle equipment cabin floor and a rail vehicle equipment cabin floor structure. Background technique [0002] In the field of rail transit, the environment under the vehicle of high-speed vehicles is complex, and it is usually necessary to set up a special equipment compartment under the vehicle for placing various equipment to ensure the operation safety of the equipment under the vehicle. For the equipment cabin, the bottom plate of the equipment cabin is the most important part. Since the bottom plate is close to the rail surface, it needs to be able to withstand the impact of foreign objects splashed by the rail surface while bearing the shock and vibration generated during the operation of the train. At present, aluminum profiles are often used to make equipment cabin floors, but aluminum profiles have the problem of heavy weight and difficult to repair af...
