Problems solved by technology
Although the photoelectric compensation device can compensate the angular displacement during low-frequency vibration, it cannot be compensated during medium and high-frequency vibration and impact
Therefore, the isolator cannot meet the requirements of the actual working state of this type of optoelectronic equipment

The invention provides a high-precision angular limiting displacement vibration isolation buffering platform for photoelectric equipment. The vibration isolation buffering platform comprises an uppermounting plate and a lower mounting plate, wherein the upper mounting plate and the lower mounting plate are connected through a plurality of vibration isolators; photoelectric equipment is mounted onthe upper mounting plate, the lower mounting plate is connected with the mounting base, the plurality of corner limiting devices are symmetrically and uniformly mounted between the upper mounting plate and the lower mounting plate along the X-axis and Y-axis directions, the corner limiting devices limits the relative corner displacement of three coordinate axes of X, Y and Z generated when vibration impact occurs between the upper mounting plate and the lower mounting plate, ensured that the upper mounting plate and the lower mounting plate always do linear relative movement in three axial directions in the vibration impact process, and the three-axial linear displacement of the corner limiting devices are larger than the limits displacement of the third axial direction of the vibration isolators. According to the device disclosed by the invention, the photoelectric equipment is effectively isolated and buffered, the angular limiting displacement of the photoelectric equipment is effectively limited, and the accurate orientation precision of the photoelectric equipment is ensured.
Description
technical field [0001] The invention relates to the technical field of vibration isolation buffering and angular displacement control of photoelectric equipment, in particular to a high-precision angular displacement vibration isolation buffer platform for photoelectric equipment, which can be widely used in sea, land and air equipment. Background technique [0002] At present, optoelectronic equipment such as inertial navigators, gyroscopes, radars, optical platforms, etc., are mainly installed on the vehicle by rigid installation, and a small amount of vibration isolation buffer system is also used for installation. [0003] The rigid installation method maintains good stability and reliability of the initial calibration coordinates and pose parameters of this type of optoelectronic equipment, but it has high requirements on the ability of the equipment to withstand strong shocks and strong vibrations. Sometimes even if their electrical properties and Structural reinforcem...
