为了防止中国科学院临近空间环境野外综合探测站(廊坊,39°N,116°E)的钠荧光多普勒激光雷达在可重新部署运输过程中震动对激光雷达系统的不良影响,保证系统测量的稳定性和精度,文中主要对钠激光雷达接收系统进行了减震设计。首先选用了空气悬挂车载底盘和对望远镜的主镜运输以及望远镜安装运输平台等进行了三级减震设计,通过仿真模拟表明通过减震设计的望远镜安装运输平台冲击位移小于望远镜的主镜运输减震设计要求;其次通过跑车实验表明通过减震设计主镜室的最大振动加速度满足望远镜运输条件设计输入要求;最后通过钠荧光多普勒激光雷达系统的观测实验进一步验证了在长途运输中减震设计的可靠性。
In order to prevent the adverse impact of sodium-fluorescence Doppler lidar near CASS (Langfang, 39 ° N, 116 ° E) on lidar system during redeployment and transportation, and to ensure that system-measured Stability and accuracy, the paper mainly designed the sodium lidar receiving system. First of all, air suspension vehicle chassis and telescope primary mirror transport and telescope installation transport platform were selected for three-level shock absorption design. The simulations show that the impact displacement of the transport platform installed by the telescope with shock absorption design is less than that of the primary mirror of the telescope Seismic design requirements; secondly, through sports car experiments show that the maximum vibration acceleration of the main mirror room through the shock absorption design meets the telescope transport conditions design input requirements; Finally, Design reliability.
