Abstract

The invention discloses a vibration damping device and method for transportation of South Pole astronomical equipment. The device comprises six active vibration dampers, an anemometer and a controller, the six active vibration dampers are mounted on the bottom surface and the side surface of a transportation flat table top of the South Pole astronomical equipment, and each active vibration damper comprises a spring, a magneto-rheological actuator, an acceleration sensor and a driver. The controller collects information of the acceleration sensors and the anemometer, feedback control is completed through system identification, predictive control and rolling optimization, interference of wind speed is compensated through PD feedforward control, and the magneto-rheological actuators are driven to act to change system rigidity and damping under the combined action of feedforward and feedback, so vibration of the flat table top in two dimensions is weakened. According to the vibration damping device and method, the bandwidth and self-adaptability of a vibration damping system are improved, feed-forward compensation is conducted on wind speed interference, and the stability and safety of astronomical equipment transportation are improved.

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...
