三轴气浮台自动调节平衡和干扰力矩测试

三轴气浮台是在地面模拟卫星姿态运动的支撑平台. 为有效进行卫星地面模拟仿真, 模拟卫星在外层空间的小干扰力矩力学环境, 首先分析气浮台扰动力矩, 针对重心相对于回转中心存在漂移时产生静态不平衡, 及主惯性轴相对于回转轴存在漂移时会产生动态不平衡的问题, 采用先手动平衡再自动平衡的方法, 调节气浮台平衡; 然后给出三自由度气浮台自动平衡动力学方程, 在平衡调整基础上, 用有效的测试手段测试气浮台的台体水平度、静不平衡力矩、干扰力矩等, 为小卫星姿态控制系统的仿真提供一个有效的、精确的实验平台. 

Adjust to the Balance of Three-DOF Air-bearing Test-platform and the Research of Disturber Torque

Three-DOF air-bearing test-platform is the key test base of simulating the satellite attitude motion for simulating the satellite emulation effective,so as to simulate the torque-free environment in the space.3-DOF air-bearing test-platform disturber moment is analysed.When there is a shift between the gravity center and the rotary center,the static unbalance appears.While a shift exits between main inertia axes and rotary axis,the dynamic unbalance appears.In addition, the principal and procedure of balanc...
