The invention provides a vibration isolation device suitable for a satellite control moment gyro, the vibration isolation device comprises a lower mounting plate, an upper mounting plate and a vibration isolation assembly, the vibration isolation assembly comprises a first vibration isolator array and a second vibration isolator array, and the first vibration isolator array is mounted between the lower mounting plate and the upper mounting plate. The second vibration isolator array is mounted on the upper mounting plate, each of the first vibration isolator array and the second vibration isolator array comprises four vibration isolators, and the four vibration isolators are arranged in parallel. According to the invention, the coupling characteristic is designed by considering the mounting requirement of the control moment gyroscope from the actual vibration reduction requirement; The installed vibration isolation assembly is symmetrically and coplanarly arranged, so that the planeness requirement of the control moment gyroscope during installation is ensured, the rigidity center passes through the mass center of the control moment gyroscope, good decoupling characteristics in all directions are achieved, the multi-direction vibration isolation effect is achieved, and more stable and more excellent performance is obtained.
本发明提供了一种适用于卫星控制力矩陀螺的隔振装置,包括下安装板、上安装板以及隔振组件,所述隔振组件包括第一隔振器阵列以及第二隔振器阵列,所述第一隔振器阵列安装在下安装板和上安装板之间,所述第二隔振器阵列安装在所述上安装板上,所述第一隔振器阵列和第二隔振器阵列均包括4个隔振器且均为并联的平行布置,本发明从实际减振需求出发,考虑到控制力矩陀螺的安装需求,对耦合特性进行设计,对所安装的隔振组件进行对称和共平面布置,既保证控制力矩陀螺安装时的平面度要求,又使得刚度中心通过控制力矩陀螺质心,具有良好的各向解耦特性,具有多向隔振效果,获得了更稳定、更优异的性能。
