摘要: 为分析隔振平台对星上飞轮扰动的衰减效果,研究了飞轮隔振平台组合系统的动力学建模问题.首先推导出含有静动不平衡量的飞轮加隔振平台组合系统的动力学模型.从模型中得出,飞轮和平台之间存在耦合;转子的静动不平衡会体现为飞轮的多项扰动力和扰动力矩.其次,对这些扰动项进行量级分析,并据此简化系统方程.最后利用数值仿真将简化模型与之前的完整模型作对比,验证了此简化模型的合理性;并通过初步的整星系统仿真,说明了隔振系统对航天器姿态稳定度的改善效果.Abstract: To analyze the attenuation effect of vibration isolation platform for reaction wheel (RW) disturbances, the dynamic modeling problem of the combined system which includes an imbalance RW and a passive Stewart platform with kinetic base platform was studied. The precise dynamics formulation was derived. The equations show that there are coupling effects between the RW and the platform, and rotor imbalance can also produce additional coupling disturbances other than tonal disturbances. The magnitudes of these disturbances were investigated and a reduction of the system model was made accordingly. Numerical simulations were conducted to compare the reduced system model to the complete one, which check the validity of the reduced model. And a primary simulation for whole spacecraft system shows that the vibration isolation system could improve the attitude stability effectively.
