Satellite platform ground simulation equipment.
Background technique
Along with the rapid development of science and technology, space flight earth observation remote sensing task is gradually towards high spatial resolution and high efficiency side
To development, and observe the high spatial resolution of remote sensing and high efficiency depend primarily on the pointing accuracy of satellite load, stability and
Quick mobility.In traditional satellite platform, the flexible appendages such as large-scale solar array and flywheel, gyro, driving mechanism
Equal movable parts are the main reason for influencing satellite load posture pointing accuracy, stability and quick mobility.
In conventional satellite design, load cabin and platform cabin are connected, and posture follows satellite platform to be controlled, load cabin
Attitude accuracy depends primarily on the attitude control accuracy of satellite platform, and the large-scale flexible appendage on satellite platform influences indirectly
The control precision of load cabin.Therefore it is difficult to realize the ultra-high stable of load posture simultaneously in such a way that load and platform are connected
Degree, superelevation pointing accuracy and superelevation agility performance.In order to improve the pointing accuracy and stability of satellite load, have to vibration
The isolation and inhibition of effect by using platform and load to be carried out to the two-body satellite form of physical separation, and then realize load
High-precision high-speed movement, it has also become one of the hot spot technology of next-generation satellite platform.In order to realize to the in-orbit of two-body satellite platform
Performance verification, the ground simulation experiment for carrying out simulated weightlessness and micro- disturbance torque space environment just become particularly important.Therefore, it needs
The ground physical emulation ground testing system for meeting movement needs is provided.
Patent document CN103514792A refers to that a kind of space six degree of freedom air bearing follow-up motion platform, the platform pass through gas
Floating technology realization two-freedom translation and three degree of freedom rotation, and it is vertical servo-actuated using the realization of fluid balance method, and then obtain
Obtain the movement simulation of spacecraft attitude under space microgravity environment.But the hydraulic-driven structure type that the patent document uses,
Due to hydraulic oil high viscosity and cause biggish viscous damping to be interfered, while being promoted using one-way hydraulic cylinder and being put down with air bearing campaign
The open type control mode that the gravity of platform balances each other has seriously undermined the response frequency and stability of plateform system；Patent document
CN104875907A refers to that a kind of narrow space heavy equipment transports installation six degree of freedom air-floated vehicle, passes through plane gas foot, front and back
The combination of one-movement-freedom-degree device, vertical shift freedom degree device and the freedom degree device that swings, realizes the six of heavy equipment
Freedom degree transports installation, but vertically moving in the air-floated vehicle, front and back overturning, left-right swinging mechanism are all made of direct contact type
Motion guide rail, and then biggish frictional force is brought, it is unable to satisfy the ground simulation requirement of micro- disturbance torque environment of spacecraft；Specially
One of sharp document CN105321398A six degree of freedom air-flotation type motion simulator, by a spherical surface air-bearing, three
Plane air-bearing and a lifting column assembly realize the six-freedom motion of platform, but the lifting column assembly in the patent is logical
The form connection outer support column and balance weight for crossing wirerope and pulley blocks, can bring biggish frictional force to interfere, and due to steel wire
Elastic deformation cause catenary motion control precision it is low, stablize the time it is long.Therefore need to design a kind of fast response time, perturbed force
Square is small, and is adapted to the novel six freedom physical simulation of verifying two-body satellite pointing accuracy, stability and quick mobility
Ground test device.
