| description | The invention belongs to aero-engines, and particularly relates to a multi-parameter frequency modulation design method for a thin-web straight gear of an aero-engine, which comprises the following steps: confirming a preliminary scheme of a gear shaft, and establishing a three-dimensional model of the gear shaft; on the basis of a preliminary scheme, modal trial calculation is carried out, the thickness of a radial plate, the tooth width size and the fillet size are sequentially adjusted till no resonance point exists in all common working rotating speed ranges, any gear can have no calculation resonance point in the working rotating speed range, gear weight increment is small, and structural improvement design can be carried out according to the analysis result in the design stage; and the possibility of resonance fatigue damage of the gear during working is reduced, so that the working reliability of the thin-web straight gear of the aero-engine is improved.
