| 中文摘要: |
| 主要从振动对光电设备成像的影响和无角位移隔振设计两个方面，综述了近年来国内外学术界对机载光电设备的隔振设计方法和技术。提出角振动较线振动对光电吊舱成像质量的影响大，光电吊舱隔振设计需重点考虑降低角振动问题。引起设备角振动的重要因素为光电设备的质心与隔振系统的刚度中心相偏离，以及各隔振器之间的刚度和阻尼不匹配，隔振系统设计时应予以关注。 |
| 英文摘要: |
| 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. |
