摘要
采用DH5922N动态信号分析系统,结合LabWindows/CVI虚拟仪器软件集成开发环境,研制了一款基于加速度计的直升机风洞试验振动监控系统,实现了试验台振动的安全监控。通过多次风洞试验,系统具有良好的适用性和可靠性,能够满足直升机风洞试验的安全需求。
In order to measure the vibration of the helicopter test in wind tunnel test accurately,and protect the safety of rotor and test rig effectively,DH5922N dynamic signal analysis system and LabWindows/CVI virtual instrument software integrated development environment were adopted to develop a helicopter wind tunnel test vibration monitoring system based on the accelerometer,which realizes the safety monitoring of the test rig vibration.Through several wind tunnel tests,the results show that the vibration monitoring system has good applicability and reliability and can meet the safety requirements of helicopter wind tunnel tests.
