Effect of qianggu kangwei formula on osteoblasts cultured in vitro under simulated weightlessness
强骨抗萎方对模拟失重条件下体外培养成骨细胞的影响
The air bearing is the most important part of an attitude control system simulator for simulating a satellite moving in the weightless circumstance . performance of a satellite attitude simulation system based on air bearing is decided by the inertia matrix and gravity disturbance torque arising from a difference between mass center and rotation center , and air bearing can be used to simulate the algorithm of on - line mass - property parameters identification on the ground . so the problem of mass - property and gravity disturbance torque identification for satellite and air bearing is studied in this thesis
气浮台能够模拟卫星在轨失重条件下的姿态运动,是卫星姿态控制系统物理仿真的核心部件,其转动惯量和质心偏移引起的重力干扰力矩等决定了基于气浮台的卫星姿态物理仿真系统的性能,并且利用气浮台可以实现卫星质量特性在线辨识算法的地面物理仿真验证,因此本文对卫星和气浮台的质量特性及干扰力矩在线辨识问题进行深入研究。
