In order to solve the difficult problems in the wind tunnel test, the common faults of the measurement system in the wind tunnel test are summarized and analyzed. By collecting and analyzing the common faults recorded in the 2-meter high speed wind tunnel test, the fault types and their treatment methods are sorted out, so that the problems can be found and solved quickly through the analysis report when the faults occur in the wind tunnel test. The application in 2 m high speed wind tunnel test shows that the method realizes the feasibility of quickly finding the key problems after the common faults occur, and provides a strong support for the safety and efficiency of wind tunnel test.
