Bamboo twined vehicle body suitable for middle-low speed electromagnetic suspension track transport vehicle and preparation method

Abstract

The invention discloses a bamboo twined vehicle body suitable for a middle-low speed electromagnetic suspension track transport vehicle and further discloses a corresponding preparation method of the vehicle body. The vehicle body comprises a vehicle body framework, outer panel skin covering the vehicle body framework and end walls arranged at the two ends of the vehicle body. The outer panel skin is manufactured by means of the method that a vehicle body core mold is twined with bamboo skin belts, meanwhile resin is soaked on the twining bamboo skin belts, and demolding is conducted after adhering and solidifying forming. The framework comprises a plurality of ring-direction beams and a plurality of longitudinal beams. A plurality of grooves matched with the ring-direction beams in position are pre-formed in the inner wall face of the outer panel skin in the ring direction, or bolts matched with the ring-direction beams in position are pre-buried in the inner wall face of the outer panel skin in the ring direction, so that the outer panel skin and the framework are fixed in an embedding joint mode through the grooves or fixed through the bolts. The vehicle body outer panel skin formed on the basis of the bamboo twining technology and the framework arranged in an optimized mode form an optimized combined structure, the tensile strength and the buffering capacity are good, and the vehicle body strength and stress requirements are met; and the structure is simple, and the bamboo twined vehicle body has the advantage that the performance of heat insulation, sound insulation and damping is prominent.

Description

technical field [0001] The invention belongs to the technical field of rail transit vehicles, and in particular relates to a bamboo winding car body suitable for medium and low-speed maglev rail transit vehicles and a preparation method thereof. Background technique [0002] The maglev train uses electromagnetic force to offset the gravitational force of the earth, and maintains a certain gap between the car body and the track through automatic control means (the suspension gap is about 1 cm), so that the train is suspended on the track. Medium and low-speed maglev transportation is a low-noise and carbon-free transportation, and it is one of the important directions for future urban transportation development. Compared with the ordinary wheel-rail subway light rail, the medium and low-speed maglev train uses the suspension frame to run on the rail, without the risk of derailment, and has the advantages of safety and reliability, short construction period, low construction c...
