| Abstract: |
| This paper reviews new worldwide advances of vibration isolation method for airborne opto-electronic pod in recent years, mainly from the influence of vibration for the imaging quality of the optoelectronic device and the method of irrotational displacement isolation for airborne optoelectronic pod. It proposes that the angular vibration has more influence on the imaging quality of the pod than the linear vibration, and the vibration isolation design of the pod should focus on reducing the angular vibration. The important factors causing the angular vibration of the equipment are the deviation between the mass center of the photoelectric equipment and the stiffness center of the vibration isolation system, and the mismatch between the stiffness and damping of the vibration isolators that should be paid attention to in the design of vibration isolation system. |
