Study of Noise Environmental Test of Airborne Equipment

The calculation method of standard test load and the structure of two kinds of testing devices were introduced,which were the progressive wave tube and the reverberation chamber with high acoustic intensity test system and testing system.The noise environmental test study was carried out based on the Fig.1 of GBJ 15017-86.The design and manufacture of test fixture,the setting and examination of the sample before noise environmental test,and the procedure of the test were explained.The acoustic field was controlled by open-loop or close-loop.The test method satisfied the requirement of the National Military Standard——GJB 150.17-86.
