Method and device for cold ejection and deceleration parking of over speed train

Abstract

The invention relates to a method and device for cold ejection and deceleration parking of an over speed train. An air compressor is used to largely redundantly preposition the super large transient energy and super large transient force in an air cylinder used for ejection. When the over speed train is ejected, the high-pressure air in the ejection cylinder enters into a air-liquid constant-ratecylinder through an ejection control valve, and the air-liquid constant-rate cylinder quickly ejects the over speed train through a connecting device; when the over speed train moves to the position of the ejection terminal, the reset air spring is touched, the mechanical connection of the coupling device of the the air-liquid constant-rate cylinder and the over speed train is relieved. The ejection control valve is closed. Timing is set. The high-pressure air in the deceleration air cylinder enters the deceleration air spring through a deceleration control valve. The deceleration air spring is connected with a blocking device; after entering into the station, the over speed train is blocked by the blocking device of the deceleration gas spring. According to the invention, aiming at the starting and stopping ends of the over speed train, the short-distance stable cold ejection starting and the short-distance stable deceleration parking are matched with the magnetic suspension system orthe air floatation system so as to achieve the maximum propelling speed.

Description

technical field [0001] The invention relates to the technical field of rapid transportation, in particular to a method and device for cold ejection and deceleration parking of an overspeed train for magnetically suspended high-speed traffic in a vacuum tube. Background technique [0002] It does not violate the basic principles of physics that superspeed trains rely on magnetic levitation and inertia to run at high speed in real tubes. The inertial flight of space objects is a precedent. Pneumatic levitation trains are also feasible for high-speed operation, and supersonic aircraft is a precedent. But the fast and stable start of the superspeed train from 0 → supersonic speed and the fast and stable stop from supersonic speed → 0 are really big problems. According to the description of "launching it to the destination like firing a cannonball" in the data of the speeding train, it obviously does not meet its safety and comfort. Objectively speaking, people have very little...

However, the fast and smooth start of the superspeed train from 0 → supersonic speed and the fast and smooth stop from supersonic speed → 0 are indeed big problems

However, according to the description of "launching it to the destination like a cannonball" in the information on the speeding train, it obviously does not meet its safety and comfort.

Objectively speaking, people have very little tolerance for this explosive acceleration (deceleration) force—it hovers between 0.2 and 1G, resulting in a large proportion of the acceleration (deceleration) section and a small proportion of the real high-speed operation period, making ultra-high speed difficult. As expected, but in fact, people have a great tolerance for gradually and steadily increasing the acceleration force. As long as an effective way and method for gradually increasing the acceleration (deceleration) force is found, the expected ultra-high speed can be achieved.
