Abstract

The invention provides a vibration isolation device for an airborne electro-optical pod. The vibration isolation device comprises an outer mounting elastic adjusting layer, an outer mounting ring, a viscoelastic damping layer and an inner mounting ring; the inner mounting ring is connected with an inner cabin, the outer mounting ring is connected with an outer cabin, and the outer mounting elasticadjusting layer can realize seamless connection between the vibration isolation device and the outer cabin; the vibration isolation device has a three-direction vibration isolation buffering effect;slotted holes are distributed in the outer mounting ring, and the rigidity of the vibration isolation device can be adjusted by designing the sizes and shapes of the slotted holes and the rigidity ofthe viscoelastic damping layer; furthermore, bosses of the inner mounting ring and the outer mounting ring mutually form a limiting and interlocking device, large displacement in three directions canbe limited, meanwhile, self-locking in an ultimate failure state can be achieved, and the equipment safety and reliability are improved.

Description

technical field [0001] The invention relates to the technical field of vibration isolation and buffering, in particular to a vibration isolation device for a photoelectric pod. Background technique [0002] The airborne optoelectronic pod is prone to vibration and shock problems under the flight environment load, which seriously affects the service life and imaging accuracy of optoelectronic equipment. In order to improve the reliability of the optoelectronic equipment in the electromechanical optical pod, it is necessary to carry out vibration isolation, buffering and installation design for the optoelectronic pod equipment as a whole. [0003] Existing vibration isolators such as wire mesh, metal rubber, and rubber all have better vibration isolation effects. However, when applied to photoelectric pod equipment, its structure is small, and the installation form is not ideal at the same time, which cannot solve the problem of vibration isolation and buffering of large phot...
