Description
Technical Field
The invention relates to the field of spacecraft physical simulation, in particular to a differential air floatation vertical control double-super satellite platform ground simulation device.
Background
With the rapid development of science and technology, the space-to-ground observation remote sensing task gradually develops towards high spatial resolution and high efficiency, and the high spatial resolution and the high efficiency of the observation remote sensing mainly depend on the pointing accuracy, the stability and the agile maneuvering performance of the satellite load. In a traditional satellite platform, flexible accessories such as a large solar sailboard and the like, and movable parts such as a flywheel, a gyroscope, a driving mechanism and the like are main reasons influencing the pointing accuracy, stability and agile maneuvering performance of a satellite load attitude.
In the traditional satellite design, a load cabin is fixedly connected with a platform cabin, the attitude of the load cabin is controlled along with a satellite platform, the attitude precision of the load cabin mainly depends on the attitude control precision of the satellite platform, and a large-scale flexible accessory on the satellite platform indirectly influences the control precision of the load cabin. Therefore, the mode of fixedly connecting the load and the platform is difficult to realize ultrahigh stability, ultrahigh pointing precision and ultrahigh agility of the load attitude at the same time. In order to improve the pointing accuracy and stability of the satellite load and effectively isolate and suppress vibration, a double-body satellite mode of physically separating the platform and the load is adopted to further realize high-precision high-speed motion of the load, and the double-body satellite mode becomes one of hot point technologies of next-generation satellite platforms. In order to realize the on-orbit performance verification of the double-body satellite platform, a ground simulation experiment for simulating the space environment of weightlessness and micro-interference moment becomes more important. Therefore, it is desirable to provide a ground physics simulation ground test system that meets the motion requirements.
Patent document CN103514792A mentions a spatial six-degree-of-freedom air-floating follow-up motion platform, which realizes two-degree-of-freedom translation and three-degree-of-freedom rotation by an air-floating technology, and adopts a liquid balance method to realize vertical follow-up, thereby obtaining motion simulation of the attitude of the spacecraft in a space microgravity environment. However, in the hydraulic driving structure adopted in the patent document, the high viscosity of hydraulic oil causes large viscous damping interference, and meanwhile, an open control mode that the thrust of a one-way hydraulic cylinder is balanced with the gravity of an air floatation motion platform is adopted, so that the response frequency and the stability of a platform system are seriously weakened; patent document CN104875907A mentions a six-degree-of-freedom air-floating vehicle for transporting and mounting heavy equipment in a narrow space, which realizes six-degree-of-freedom transportation and mounting of heavy equipment through a combination of a planar air foot, a front-back movement degree-of-freedom device, a vertical movement degree-of-freedom device and a left-right swinging degree-of-freedom device, but vertical movement, front-back overturning and left-right swinging mechanisms in the air-floating vehicle all adopt direct contact type motion guide rails, thereby bringing greater friction force and failing to meet ground simulation requirements of a micro interference torque environment of a spacecraft; in patent document CN105321398A, a six-degree-of-freedom air-floating motion simulator realizes six-degree-of-freedom motion of a platform by means of a spherical air-floating bearing, three planar air-floating bearings and a lifting column assembly, but the lifting column assembly in the patent is connected with an outer support column and a balance block in a form of a steel wire rope and a pulley block, which can bring large friction interference, and the elastic deformation of the steel wire causes low control precision and long stabilization time of vertical motion. Therefore, a novel six-degree-of-freedom physical simulation ground testing device which is high in response speed, small in interference torque and suitable for verifying pointing accuracy, stability and agile mobility of a double-body satellite needs to be designed.
