Abstract

The invention provides a carbon fiber composite material end wall structure for subway, which includes an end wall interlayer structure, a grounding copper bar, a drainage pipe, a wiring trough installation hanger, an electrical cabinet installation seat and a cable tie rod. The end wall interlayer structure includes an integral reinforcement frame, Honeycomb sandwich core, end wall inserts, inner skin and outer skin, the overall reinforcement frame, honeycomb sandwich core, and end wall inserts are all built between the inner skin and outer skin, and the overall reinforcement frame adopts an integrated hat-shaped structure , the two sides of the overall reinforced frame are respectively provided with honeycomb sandwich, the end wall inserts are set in the honeycomb sandwich, the end wall inserts are provided with threaded holes, and the grounding copper bar is connected to the inner skin of the end wall sandwich structure by glue riveting The upper part of the side; this kind of carbon fiber composite material end wall structure for subway can give full play to the characteristics of high specific strength and large specific modulus of carbon fiber composite materials, and the effect of weight reduction is outstanding; the integrated design simplifies the redundant traditional welding structure , reduce the assembly workload.

Description

technical field [0001] The invention relates to a carbon fiber composite material end wall structure for a subway. Background technique [0002] At present, rail transit equipment has become a beautiful "business card" for Chinese technology, Chinese equipment, and Chinese manufacturing. With the rapid development of domestic and foreign rail transit fields, the lightweight of rail transit has received more and more attention. The light weight of rail transit has particularly important practical significance for vehicle weight reduction, speed increase, noise reduction, energy consumption reduction, and ride comfort improvement. [0003] The end walls are located at the front and rear ends of the subway car body, forming a closed space with the car body and the underframe, and are used for the installation of through passages between adjacent car bodies to facilitate passengers to pass through. In addition, small parts such as installation cranes and electrical cabinet ins...
