Abstract: In order to study the application characteristics of three typical pressure scanning valve system in wind tunnel environments and provide technical support for related experiments, a systematic research and comparative analysis method was adopted.Wind tunnel tests were conducted based on the PSI 9116 electronic pressure scanning valve, DTC Initium multi-parameter data acquisition system, and Optimus intelligent measurement and control system. At the same time, a universal force and pressure measurement software platform for high-speed wind tunnels was developed, and a wind tunnel test performance evaluation system was established to verify the system accuracy. The quantitative performance comparison results of the three systems were obtained, providing a scientific basis for the selection of wind tunnel test equipment.

引言
風洞中的壓力主要采用壓力掃描閥進行測量,因為其具有小型化、精度高、通道數多等優點,從而在試驗中得到廣泛應用[1]。隨著對試驗數據質量要求的日益提高,所有測量數據必須滿足質量管理體系標準,在測量過程中能控制精準度,然而傳感器在現場使用環境與在實驗室中的檢定環境有很大不同,壓力測量系統在現場環境下將受到溫度、濕度變化等環境因素影響[2],因此通常會在風洞試驗前對系統進行性能評估,評估的內容包括壓力測量系統的全量程性能測試、使用前性能的確認、系統的運行狀態監測等。其中,壓力掃描閥系統的全量程性能測試是評定試驗中測量數據可靠性的基礎。通過測試,能夠直觀地得到試驗系統的測量誤差,建立完整的溯源鏈,提升試驗數據的可信度[3]。對比分析三類掃描閥系統的性能特點,使用最新開發的高速風洞測力測壓通用平臺軟件對其進行性能評估,根據其設備特點和評估情況應用于各類風洞試驗。
