| description | The invention discloses a large astronomical telescope altitude shafting hydraulic auxiliary control method and system. The method comprises steps that a self-adjustment step hydraulic oil is allowedto slowly flow in a pipeline when an axis diameter of a telescope height axis generates symmetric movement relative to a Y axis so as to reduce the acting force between an altitude axis structure anda lateral constraint; when an external unstable load acts on the height axis structure or the azimuth axis braking torque is transmitted to the height axis structure to generate rotational motion, thefluid in the system cannot move, and the amplitude of the rotational motion of the height axis structure relative to the azimuth axis system is inhibited and reduced; when the height axis normally moves in a tracking mode, fluid in a hydraulic oil way cannot move, and the movement of the height axis structure in the positive and negative X-axis directions is further limited. When a pitch angle ofthe height axis is changed, |
