基于功率流理论的星上飞轮隔振效能研究

摘要

To analyze the attenuation of the reaction wheel disturbance in the vibration isolation system, the isolation performance of the satellitic flywheel is analyzed based on the power flow theory. The dynamic model of the system under a flexible base is first built. Then the power flow expressions of this system are derived and the effect of the structural parameters of the isolation device on the power flow transmitted into the subsystems is analyzed by the numerical simulation. The results can be used in the optimization design of the system structure parameters.%为分析隔振系统对星上飞轮扰动的衰减效果,需要对隔振系统的隔振效能进行评价.文章运用功率流理论进行飞轮隔振效能研究.建立柔性基础上飞轮隔振系统动力学模型,推导出系统的功率流传递表达式,并通过数值仿真计算初步分析了隔振系统结构参数对功率流传递谱的影响.研究结果可为系统结构参数的优化设计提供参考依据.
