| Abstract: |
| 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. |
