Abstract

The invention discloses an aluminum matrix composite material rail vehicle. The aluminum-based composite material rail vehicle includes a car body, which is mainly composed of arc roof profiles, air-conditioning panel profiles, side wall panel profiles, chassis floor profiles, two left and right roof side beams, and two left and right bottom The box structure formed by the connection of side beams; the air-conditioning panel profile is mainly formed by welding the middle profile of the air-conditioning panel and the connecting profiles of the left and right air-conditioning panels; The connection profiles of the side wall panels are welded and connected, and the bottom frame floor profiles are mainly formed by welding the middle profile of the bottom frame floor and the left and right bottom frame floor connection profiles; the middle profile of the air conditioning panel and / or the side wall panels The intermediate profile and / or the intermediate profile of the underframe floor is a nano-ceramic aluminum alloy profile. The invention can realize further lightening of the vehicle body.

Description

technical field [0001] The invention relates to an aluminum-based composite material rail vehicle, which belongs to the technical field of rail transportation vehicles. Background technique [0002] With the development of modern science and technology, the performance requirements of light weight, vibration and sound insulation of rail train vehicles have become more stringent, especially in non-tunnel sections inside cities, the requirements for vehicle wheel-rail noise are higher. In the field of rail train car body steel structure, various research institutes and manufacturers have been constantly trying to use new materials to improve performance indicators. [0003] In recent years, carbon fiber car body structure is a hot field of car body lightweight research. The patents with application numbers CN201520712628.4, CN201611093476.X, and CN201620863664.5 all involve carbon fiber composite car body structures. Carbon fiber itself has the characteristics of high specifi...
