| 中文摘要: |
| 根据经典隔振理论、橡胶材料本构模型以及应用有限元仿真技术对某卫星惯性设备进行隔振分析，研制一种三向等刚度橡胶减振器。结果表明，橡胶减振器采用宽温域高阻尼硅橡胶材料与金属材料复合制备，在三向振动频率为（75±5） Hz以及冲击环境下，安装橡胶减振器设备的振动响应量值由19g（g为重力加速度）降至7.7g，冲击量值由8 000g降至500g，满足惯性设备的减振需求。 |

| According to the classical vibration isolation theory，rubber material constitutive model and finite element simulation technology，the vibration isolation analysis of a satellite inertial equipment was carried out，and a three-dimensional equal stiffness rubber shock absorber was developed.The results showed that the rubber shock absorber was made of wide temperature range and high damping silicon rubber and metal materials.Under the three-dimensional vibration frequency of （75±5） Hz and impact environment，the vibration response value of equipment with rubber shock absorber was reduced from 19g（g was gravity acceleration） to 7.7g，and the impact value was reduced from 8 000g to 500g，which met the damping requirements of inertial equipment. |
