| Abstract: | The gear dynamic stress measurement is a necessary means to understand the vibration characteristics of gear in working state.The dynamic stress test has been performed for a turbofan engine accessory drive gear of two design schemes.The technique applying strain gauge and slip ring to measure gear dynamic stress and frequency is introduced.The dynamic stress data of the gear at operational speed have been acquired.The test results are preliminarily analyzed.This test promotes experiences in the dynamic stress test technology of aero-engine accessory drive gears.This research is of significance for studying the vibration characteristics of the accessory drive gears in rotational state. |
