In the course of the study, the rendezvous and docking technology validation fluid control system thecorrectness, to improve the simulation system test is the necessary.reliability spacecraft in orbit in order to reduce the risk of aircraft control, physical simulation of the system test is necessary. Space environment has two main characteristics: weight loss and vacuum. Flotation units formed by compressed air gap between the air bearing and the bearing film, so that the suspension of the air bearing table to counteract the effects of gravity, and to achieve the approximation of the relative movement of the friction conditions, the analog outer space spacecraft interferencetorque mechanical environment. As the spacecraft control system, the the flotation test stand can simulate zero gravity conditions, the ideal platform for Spacecraft Attitude Dynamics and Control System, the core component of the physical simulation of the conditions on the ground in orbit spacecraft attitude motion. Accordin to the thery on the spacecraft attitude kinetics the formual for the platform structure mass-center displaysment and for the counter-weight are deduced. Therefor the calculation formula for unbalance torque arising form self-weight deformation of platform is obtained. Can be analyzed according to the accurate modeling of the quality characteristics of the rotating part of the kinetic equati
