Description
Technical Field
The invention relates to the field of spacecraft physical simulation, in particular to a solar wing suspension type air floatation unfolding motion device based on active/passive magnetic pretension.
Background
In order to ensure the normal operation of the spacecraft in space, energy needs to be provided. The solar wing is used as an energy acquisition device of the spacecraft in an on-orbit state, and the continuous supply of energy in the spacecraft cannot be avoided from the smooth unfolding and normal work of the solar wing. Because satellite fault maintenance is extremely difficult in the outer space environment, before the spacecraft enters the space, ground tests are needed to be carried out on the solar wing to verify the reliability of the deployment of the spacecraft. The solar wing is in a zero gravity state in outer space, so that in the process of ground test, gravity compensation needs to be carried out by a series of means so as to simulate the on-orbit state of the solar wing as much as possible.
For the ground simulation device developed by the solar wing, the gravity compensation is generally carried out at home and abroad by methods such as a suspension wire weight distribution method, an air floatation method and the like. The suspension wire counterweight method generates vertical upward tension through the suspension wire to suspend the solar wing and other equipment. The method is easy to realize, the test is not limited by space and time, the manufacturing cost is not high, and the method has the advantages of convenient maintenance, not strict requirement on the size of a test object and the like. For example, patent document CN105501472A discloses a hanging device for simulating two-dimensional expansion of a solar wing on the ground, which realizes two-dimensional expansion of the solar wing by moving a short guide rail on a long guide rail, and can solve the problem of large impact on the solar wing during the expansion test of the existing hanging device, improve the repeated stability of the expansion test, and reduce the additional damping of the ground test equipment. However, the mechanical mechanism of the equipment is usually complex, has large frictional resistance and low simulation precision.
Further, the air floatation method is characterized in that on a smooth platform, the air pressure is utilized to generate upward lifting force to compensate the gravity of equipment such as solar wings through pneumatic equipment, so that an environment with zero gravity is formed in a limited space, and microgravity simulation and low damping movement required by space mechanism testing are realized. The air floatation device has simple mechanism, low cost, and can be built in a short time, and the air floatation device has strong bearing capacity and high compensation precision, for example, patent document CN103946569A mentions a static pressure air bearing structure, by arranging a magnetic force generating part composed of a cylindrical permanent magnet in the middle of a compressed air supply part, and forming magnetic pre-tightening on a corresponding magnetized part of the static pressure air bearing structure, stable bearing can be obtained by adapting to load change, and the size and weight of the device using the bearing can be reduced. For example, patent document CN2679414Y discloses an air bearing floating block, which obtains a pre-tightening effect through the adsorption of a low-pressure cavity, thereby simplifying the bearing structure and ensuring more stable and reliable operation. However, in the above design, the air bearing is directly mounted at the lower end of the solar wing, so that the disturbance of the overturning moment is easily caused in the unfolding process of the solar wing, and the unfolding motion effect is affected.
