| Abstract: |
| Objective To verify compatibility and matchability of vibration parameter measuring system of air vehicle. Methods A comparative test scheme for vibration parameter measuring system was designed with consideration of the effects of the dynamic environment. Sensitivity inspection and vibration test with various conditions were carried out. Vibration acceleration response of the measuring system was obtained. The test control output were compared with measuring result of vibration environment measuring system and ground reference system of air vehicle. Results With the exception of Y1 channel, the errors for other channel results of the measuring system were smaller than 5% with the comparison of test control output results and ground reference results. The maximum error for Y1 channel was 27.2%. According to the further analysis, the error was caused by the sensitivity settings. Conclusion The comparative test can be utilized to demonstrate the compatibility and matchability of measuring system. Through the test results analysis, the measuring error for vibration parameter measuring system of air vehicle can be determined. It can provide data support for the application of the measuring system. |
