摘要
为了完成土壤水探测的外场挂载试验,增大土壤水探测被动天线的扫描范围,设计了一种扫描驱动机构,并利用三坐标测量仪对其转动精度进行了测量,此机构能够实现20°~34°范围动态扫描,定位精度及重复定位精度≤0.1°,相关技术指标达到了应用标准,圆满完成了挂载试验。本文为相关挂载试验扫描驱动机构设计提供了借鉴,为扫描驱动机构转动精度测量提供了一种测量方法。
A scanning driving mechanism is designed to complete the field mount experiment of soil water detection and increase the scanning range of passive antenna of soil water detection. The rotation accuracy of the system is measured by the CMM. This mechanism can realize dynamic scanning in the range of 20°~34°, with positioning accuracy and repeated positioning accuracy of 0.1°. The relevant technical indicators have reached the application standards and successfully completed the mount test. This paper provides a reference for the design of the relevant experimental driving scanning mechanism and a measurement method for the accuracy measurement of the scanning driving mechanism.
