摘要/Abstract

摘要：

为了防止车载多普勒测风激光雷达运动过程中振动对系统的不良影响，保证系统测量的稳定性和精度，对车载测风激光雷达中的机柜和光学平台进行隔振设计。选用IDC公司SB型和M型金属钢丝绳隔振器分别作为机柜和光学平台的隔振器并合理布置，通过计算可得峰值响应频率都小于干扰频率，冲击位移小于隔振器最大形变量，通过隔振效率和干扰频率的关系曲线图发现隔振效率达80%以上。最后，通过隔振前后激光雷达锁频实验效果对比可以看出隔振系统安装后锁频效果有了显著提升，通过运动中测量的1 km高度径向风速正弦曲线拟合进一步验证了在运动测量中隔振设计的可靠性。

Abstract:

In order to avoid adverse vibration influence on mobile Doppler wind lidar when it is moving and ensure measurement's stability and accuracy, a vibration isolation system is designed for cabinets and optical table of mobile wind lidar. SB and M series wire rope isolators of IDC company are respectively selected as the isolators of cabinets and optical table. By calculating, the peak response frequency is less than disturbing frequency and shock displacement is less than the max deflection of the isolators. The relation graph between vibration isolation efficiency and disturbing frequency illustrates that the vibration isolation efficiency is more than 80%. Finally, comparing the locking frequency effect in the same vibration environment before and after vibration isolation system installed, it is obvious that the vibration isolation system improves the frequency stability. It is further certified the reliability of isolation by sine curve fitting of light of sight (LOS) velocity at the elevation of 1 km during moving measurements.

Key words: mobile Doppler wind lidar, cabinet; optical table, vibration isolation design, frequency locking; moving measurements
