双光束激光多普勒测速实验系统的不确定度分析
Analysis of Uncertainty of Double Beam Laser Doppler Velocity Measurement System
摘要
Abstract
Laser Doppler velocity measurement technology has been widely used in the flow velocity measurement To reduce the measurement error of Double Beam Laser Doppler Velocity Measurement System, in accordance of procedures and methods of measurement uncertainty provided by JJF1059-1999, the main sources of uncertainty in the flow velocity measurement were analysed from two aspects, one is the mathematical model, and the other is the measurement methods. A type and B type assessment were adopted, evaluation of uncertainty components in measuring results is obtained, and then combined standard uncertainty and extended uncertainty are got.关键词
