A method for simulating the free boundary condition of satellite on orbit

  • 摘要: 随着观测精度的提高,卫星观测设备对微振动愈加敏感,需要在地面开展卫星在轨微振动环境模拟试验及测试验证,而卫星在轨自由边界条件的模拟对于提高地面试验的有效性至关重要。文章提出了一种低频弹性支撑方法,用于模拟卫星在轨飞行时的自由边界条件;并基于该方法,设计和研制了一套模拟试验装置,通过模态和频率响应分析以及型号的整星微振动模拟试验,评估了模拟自由边界条件对卫星动力学特性的影响,也证明了低频弹性支撑模拟方法的有效性。
    Abstract: With the enhanced requirements of the observation accuracy and the sensitivity to the micro-vibration of the observation payload, the on-orbit free boundary condition simulation for the spacecraft in the micro-vibration ground simulation test becomes more important. A method of the low frequency elastic suspension is proposed to simulate the free boundary condition of the on-orbit satellite. And a low frequency elastic suspension device is developed based on this method, and is applied to evaluate the influence of the simulated free boundary condition on the dynamic characteristics of the satellite by the modal and frequency response analyses. The application of this device in an actual micro-vibration test of a satellite shows that the method of the low frequency elastic suspension for the satellite is reliable.
