| description | The invention provides a large foundation optical infrared telescope hydraulic damping vertical shock isolation device which comprises a throttling check valve and a bag type energy accumulator. The bag type energy accumulator is connected with a hydraulic oil way of a telescope azimuth axial static pressure oil pad through the throttling check valve to form a complete hydraulic system; when the earthquake load exceeds a preset value, the throttling check valve is automatically opened to connect the bag type energy accumulator into the hydraulic loop in the static pressure oil pad, and at the moment, the bag type energy accumulator starts to change the rigidity damping of a telescope system, so that the resonant frequency of a main structure of a telescope avoids a dangerous acceleration peak value of a response spectrum. According to the device, high tracking and guiding performance can be satisfied during telescope observation, and the allowable acceleration limit and strength requirements of an optical ins |
