Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] A front and rear structure of a vacuum tube high-speed maglev train, comprising a head car 2 and a tail car 5 of a maglev train running on a track 7 in a vacuum pipe 3, the head car 2 is connected by an intermediate car 4 and a tail car 5, and the head The front 1 of the car 2 adopts an upturned streamlined structure. The front 1 is divided into three types: short head, middle head and long head. It is selected and used according to the technical requirements of train operation. The length of the short head 1 is less than or equal to that of the vehicle. section diameter, such as figure 1 shown. The length of the front 1 of the middle head is greater than the diameter of the vehicle section but less than twice the diameter of the vehicle section, such as figure 2 shown. The length of the front 1 of the long head is greater than or equal to ...

A train head and tail structure of a vacuum pipeline high speed maglev train comprises a head train and a tail train, the head train and the tail train of the maglev train run in a vacuum pipeline, the head train is connected with the tail train through middle trains, the train head of the head train is of a cocking-up streamline structure, namely, the conical central line or the elliptical conical central line or the wedge-shaped central line of the train head is arranged above the central line of the cross section of the train, the train tail of the tail train is of a cocking-up streamline structure, namely, the conical central line or the elliptical conical central line or the wedge-shaped central line of the train tail is arranged above the central line of the cross section of the train, when the train runs at high speed, component resultant force of aerodynamic force of the train in the perpendicular direction cocks up, therefore, the weight of the train is counteracted, the requirement of the train for maglev force is reduced, and running cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of vacuum pipeline traffic vehicle structure and aerodynamics, and in particular relates to a front and rear structure of a vacuum pipeline high-speed maglev train. Background technique [0002] Vacuum tube transportation is a new type of transportation system that has not yet been implemented. It is composed of subsystems such as pipelines, magnetic levitation tracks, linear motor drive systems, stations, and vehicles. During operation, a certain vacuum is drawn in the pipeline to allow the maglev vehicle to run under the drive of the linear motor. Due to the elimination of air resistance and mechanical friction resistance, vehicles can travel at super high speeds in it. [0003] Evacuating the pipes takes power and takes time. The higher the vacuum degree, the more power consumption and time consumption of vacuuming, the higher the cost of maintaining the vacuum, and the higher the mechanical requirement...
