摘要
近年来由于人类生产活动日益加剧,引起的大气气溶胶和臭氧等大气粒子含量的变化对全球气候变化有着重要影响。为了监测上述大气粒子含量,在总结国内外研究现状的基础上,提出使用合理的温控结构来设计制造一款新型多波段太阳辐射测量仪,用来适应国内纬度跨越大、温差大的工作环境。新型太阳辐射测量仪涵盖可见-红外波段,采用九个带通滤光片分别对应两个光电探测器的结构,可以避免探测器相互定标引起的定标误差并减少定标工作量。经ANSYS Workbench热-力耦合仿真,上述太阳辐射测量仪所采用的温控结构在两个极端温度条件下的变形量满足设计要求。
In recent years, due to human production activities, the content of atmospheric particles such as aerosols and ozone has changed, which has an important impact on global climate change.In order to monitor the above-mentioned atmospheric particle content, based on summarizing the research status around the world, this paper proposed a method for designing and manufacturing a new multi-band solar radiation measuring instrument with a reasonable temperature control structure.And the measuring instrument could adapt to the working environment with large latitudes and large temperature differences in our country.The solar radiation measuring instrument uses 9 filters to obtain 9 spectral channels within visible-infrared bands and receives radiation through visible and infrared photodetectors respectively, which can avoid calibration errors caused by the mutual calibration of the detectors and reduce the workload.The thermal-force coupling analysis by ANSYS Workbench shows the temperature control structure of the solar radiation measuring instrument meets the design requirements in two extreme temperature conditions.
