Abstract
In the process of the re deployment, in order to prevent the adverse effects and assure the stability and accuracy of the sodium Doppler fluorescence lidar in the near space environment of the Chinese Academy of Sciences(Langfang, 39N, 116E), the shock absorption design of the receiving system in sodium lidar was mainly carried out. Firstly, the three-level shock absorber design was carried out by selecting the air suspension chassis, the main mirror of the telescope, and the platform for the installation of the telescope. Through simulation, it was found that the impact displacement of the telescope platform is less than the design requirements of the primary mirror of the telescope. Secondly, by the sports truck experiment, the maximum vibration acceleration of the main mirror chamber was found to meet the requirements of the design input of the telescope. In the end, the reliability of shock absorption design of the long distance transportation is further verified by the observation experiment of the sodium doppler fluorescence lidar.
