Abstract

The invention discloses a vibration reduction device and method for the transportation of Antarctic astronomical equipment, including six active vibration absorbers, anemometers and controllers installed on the bottom and side surfaces of the Antarctic astronomical equipment transportation platform, each active vibration reduction All actuators include springs, magneto-rheological actuators, acceleration sensors and drivers. The controller collects the information of the acceleration sensor and the anemometer, completes the feedback control through system identification, predictive control and rolling optimization, and compensates the disturbance of the wind speed through the PD feedforward control, and the feedforward and feedback work together to drive the magneto-rheological actuator action change system Stiffness and damping, thereby attenuating the vibration of the flat deck in two dimensions. The damping device and method proposed by the invention not only improve the bandwidth and adaptability of the damping system, but also perform feed-forward compensation for wind speed disturbance, thereby improving the stability and safety of astronomical equipment transportation.

Description

technical field [0001] The invention relates to the field of Antarctic astronomical equipment transportation, in particular to a vibration reduction device and method for Antarctic astronomical equipment transportation. Background technique [0002] China's Antarctic Kunlun Station has a high altitude, low temperature, and good atmospheric seeing, making it an excellent site for astronomical observation. In order to make full use of the excellent observation environment of the Kunlun Station, China has built a batch of telescopes at the Kunlun Station in Antarctica. To install, operate and maintain the telescope at Kunlun Station, it is necessary to transport the telescope and other sophisticated astronomical equipment to the site. However, transporting astronomical equipment from China to the Kunlun Station in Antarctica requires long-distance transportation by land, sea, and snow in the Antarctic inland. Among them, there is a total of 1,250 kilometers from Zhongshan Sta...
