探讨了热气候风洞实验台环境测控系统动态工况的误差,对系统各环境参数(温度、湿度、辐射照度和风速)的测量不确定度进行评定。通过分析影响系统控制不稳定的因素,找出其规律性,并给出改善建议。
This paper discussed the dynamic condition s error of environmental measurement and control system of hot climate wind tunnel laboratory,and evaluated the environmental parameters (including temperature,humidity,solar radiation and air velocity) metrical uncertainty,then through the analysis of influencing factor of system control,found out its regularity and gave recommendations for improvement.
