Electromagnetic upcast microgravity device and control method thereof and electromagnetic upcast microgravity system

Abstract

An embodiment of the invention relates to an electromagnetic upcast microgravity device and a control method thereof and an electromagnetic upcast microgravity system, wherein the electromagnetic upcast microgravity device comprises an electromagnetic launcher, a speed sensor and a controller, wherein the speed sensor is used for monitoring speed of the electromagnetic launcher to obtain operatingspeed and transmitting the operating speed to the controller, and the controller is used for comparing the first operating speed received, to a first speed threshold preset, and controlling the electromagnetic launcher to launch with a load module; when the electromagnetic launcher with the load module is in free-falling motion, the controller is also used for comparing second operating speed with a second speed threshold preset, and producing braking force for the electromagnetic launcher, when the second operating speed is equal to the second speed threshold, to control the electromagneticlauncher to enter an electromagnetic braking decelerating mode. Upcast launching is performed in electromagnetic force mode; therefore, efficiency is improved, and full-process control is achieved.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of design space, in particular to an electromagnetic upward throwing microgravity device, a control method and a system. Background technique [0002] It is understandable that there are two application requirements for ground microgravity simulation: first, for space microgravity science. Microgravity science includes many disciplines such as space life, microgravity fluid physics, microgravity combustion, space materials, and basic physics, as well as new technology experiments in space in many fields. Scientific experiment satellites, space laboratories, and space stations are used as experimental platforms for long-term operation in orbit, which can provide a high level of microgravity, but the development requirements are high, the cost is high, and the opportunities are scarce. Many experiments can obtain valid experimental results through short-term microgravity environments, and...

Problems solved by technology

Several methods have their own advantages and disadvantages: sounding rockets have the longest time, but the launch cost is too high, no less than microgravity satellites; weightless aircraft can provide more than 20 seconds of microgravity time, and can carry larger loads, but microgravity The level is up to 10-3g, which is also relatively expensive; if the drop tower adopts a double cabin method, it can reach the order of 10-5~10-6, but the microgravity time is too short

Chemical energy explosive ejection and steam energy ejection can provide greater force, but the utilization rate of stroke efficiency is low and the controllability is poor; hydraulic energy can use the hydraulic cylinder with low acceleration of the pulley transmission mechanism, and the straight-top high-speed hydraulic Cylinder solution, but the stroke is relatively short; using direct drive motor for traction, the requirements for the conveyor belt are too high when the distance is relatively long, and the output force provided is relatively small
