Glass fiber reinforced plastic air duct for rail vehicle

Abstract

The invention provides a glass fiber reinforced plastic air duct for a rail vehicle. The glass fiber reinforced plastic air duct for the rail vehicle comprises multiple sub air ducts; the sub air ducts comprise an air inlet duct, a horizontal air duct, a bend air duct and an air outlet duct; the air inlet duct is connected with the air outlet duct through the bend air duct and the horizontal air duct; each sub air duct is connected by using a flange so that the air duct is connected to form a whole body; the connecting part of each sub air duct is in sealed connection; rigid connecting pieceshaving effects of air duct main frameworks are arranged at the connecting parts of the air inlet duct, the air outlet duct and a vehicle body; the rigid connecting pieces are bonded and embedded in the pasting process of the air inlet duct and the air outlet duct; structural adhesive layers are arranged on one surfaces of the rigid connecting pieces; and embedded layers are arranged on the other surfaces of the rigid connecting pieces. According to the glass fiber reinforced plastic air duct for the rail vehicle, the integral intensity of the air duct can be enhanced, outside forces borne on the rigid connecting pieces can be completely transmitted to an air duct body, the connecting strength is guaranteed, the appearance is beautiful, the integral strength and airtightness of the structure can be guaranteed, and good sound insulation and heat insulation performance can also be guaranteed.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a glass fiber reinforced plastic air duct for rail vehicles. Background technique [0002] Urban rail vehicles use air ducts to connect the driver's cab and vents, which are mainly used for dispersion and ventilation, and are also one of the main sources of noise pollution. [0003] Traditional air ducts are generally made of aluminum alloy materials and laminated panels. Aluminum alloys are not conducive to forming special-shaped parts, and the sound insulation and heat insulation effects are not good. High cost and other defects. However, the air duct is made of laminated boards, the main structure needs to be spliced ​​and combined, and the overall strength is not good. Therefore, there is an urgent need to develop a novel air duct for rail vehicles. [0004] In view of this, the existing problems are studied and improved, and a glass fiber reinforced plastic ai...
