摘要
整星振动隔离是降低作用于卫星的振动载荷的有效方法。本文了采用多杆隔振平台来实现整星隔振,利用牛顿欧拉法建立了考虑基础运动和支杆转动惯量的隔振平台的动力学模型,分析了平台放置刚性卫星和柔性卫星的振动传递率,分析结果表明隔振平台可以有效的隔离来自于基础的振动。
Whole-spacecraft vibration isolation is a direct and effective approach toward improving the dynamic environment that a spacecraft experiences during its journey to the orbit. A multi-strut vibration isolation platform with base excitation is modeled by Newton-Euler method. The transmissibility of the platform with rigid and flexible spacecraft is calculated, and the results show that multi-strut platform enables to isolate vibration effectively to improve the dynamic environment of satellite.
