Research on the Influence of Different Test Elements on Vibration Test Results
According to GJB 150.16A-2009"Laboratory environmental test methods for military material--Part 16:vibration test",by selecting the characteristic vibration level,the influence of the selection of fixing mode,the layout of piezoelectric sensor and the selection of test fixture on the test results under the same test conditions is analyzed and discussed.The test results show that under the same test magnitude,when the piezoelectric sensor is connected directly with the moving coil and the piezoelectric sensor is arranged near the center of the moving coil,the data deviation of the collection point is the best.
