Abstract

Abstract: The accessory drive gear of small aviation turboshaft engine has a high speed. It is difficult toavoid all of the vibration modals completely within the range of running speed. It is easy to generate travellingwave vibration of nodal diameters. In order to obtain the vibration characteristics of gear in working state，and pro. vide data support for the design of aero-engine accessory drive bevel gears，a method of noise measurement based on acoustic waveguide and the technique of measuring the dynamic stress of gear by strain gauge were ap.plied. The resonant speed and frequency also the dynamic stress data of the gear at full range of speed have beenacquired. The tests results showed that it is usefully obtained travelling wave resonant speed and frequency byacoustic waveguide. The strain gauge can accurately measure the dynamic frequency of the bevel gear when thetravelling wave vibration is generated. The bevel gear had a variety of travelling wave vibration at operationalspeeds. The maximum frequency amplitude of dynamic stresses was 115MPa，and it existed in backward travel. ling wave vibration of the 5th nodal diameter.
