摘    要:传统卫星适配器由于其刚度非常大,导致其不具有任何隔振效果。所以提出了一种新型整星隔振器,这种新型整星隔振器可以对刚度进行设计以满足卫星、隔振器耦合系统对固有频率的需要。基于可靠性理论和实验数据,讨论了这种整星隔振器的刚度特性。数值模拟和实验结果都表明,通过修改隔振器肋板及相应参数,卫星-隔振器耦合系统的固有频率可以控制在很大的范围之内。同时,也论证了耦合系统的固有频率控制效果。

Abstract:The traditional payload attaching fitting (PAF) does not provide any vibration isolation, because of its large stiffness. Whole-spacecraft vibration isolation is a direct and effective approach to assure the successful launching and orbit insertion of a spacecraft. In view of the problems of stiffness and vibration isolation design, for which the designers care most, the study of whole-spacecraft vibration isolator (WSVI) consists of two parts. In the first part, the stiffness feature of the WSVI is studied...
Keywords:stiffness  whole-spacecraft vibration isolator  reliability  natural frequency  transmissibility
