Satellite orbit free boundary condition means

The present invention discloses a satellite orbit free boundary condition means, including satellite mating plate, a support spring, satellite Ping Heng adjustment means, limiting the protection device and the support plate, the support plate and the mating plate satellite upper and lower portions of the machine according to the satellite provided corresponding to the structure, the common circular ring, a plurality of support springs are respectively fixedly connected to two ends of the annular portion between the abutment plate and the support plate satellite and evenly distributed, to elastically support the satellite about the annular portion; the number of support corresponding to the satellite number of springs secured Ping Heng adjustment means is provided between the support base and the spring support plate, the inclination of the satellite to the simulation device by adjusting the eccentricity of satellites supported by the support spring, so that after receiving the satellite to maintain the level of the simulation apparatus. Simulation apparatus according to the present invention is to improve the dynamic tests of satellite technology, especially to meet the high accuracy satellite observation satellites orbit dynamics during development and environmental needs verification test tracks the minute vibrations of the ground.
