Embodiment 1
[0048] Such as Figure 1-Figure 5 As shown, a device for adjusting pressure, reducing vibration and stabilizing an optical table 3 includes a lightweight optical table 3, a shock absorber 2, an air pressure controller 5 and a buffer limiter; the optical table 3 is connected to the shock absorber 2, and the vibration reduction Device 2: Used for vibration reduction of the optical table 3; the shock absorber 2 is connected to the air pressure controller 5 through an internal pipeline, and the air pressure controller 5 is used to control the internal gas pressure of the shock absorber 2 in real time; the buffer limiter is set on the optical table Around the platform 3, the surroundings of the optical platform 3 are constrained by a buffer limiter, and the optical platform 3 is protected by a buffer limit when the movement carrier changes suddenly.
[0049] Several independent additional air chambers are arranged inside the optical table 3, and the independent additional air chamber...
Embodiment 2
[0055] This embodiment is similar to Embodiment 1, the difference is that:
[0056] The shock absorber 2 is fixed on the installation platform 4 in a sunken installation manner. The sunken installation can lower the center of gravity of the optical table 3 and ensure that the center of the optical axis of the optical system 7 is as consistent as possible with the center of the visible window. Such as Figure 6 In the part A shown, the shock absorber 2 mainly supports and damps the four corners of the optical table 3 .
[0057] The optical system 7 on the optical table 3 is all ground test equipment, the external dimensions and weight of the equipment cannot be changed, only the weight of the optical table 3 and the vibration reduction and stabilization system can be reduced. Through a comprehensive comparison of several suitable materials for engineering applications, aviation aluminum is selected as the material of the optical table 3, which not only ensures the rigidity of...
