Aviation gear dynamics modeling method considering structural parameters

Abstract

The invention belongs to the technical field of gear transmission simulation, and relates to an aviation gear dynamics modeling method considering structural parameters, which comprises the following steps: 1) acquiring gear structural parameters; 2) calculating strain energy of gear structure parameters; 3) enabling the gear teeth to be equivalent to a cantilever beam with a fixed root circle, and calculating the rigidity generated by deformation of the engaged gear teeth; 4) obtaining the comprehensive synthetic rigidity of the whole gear pair; (5) the strain energy of the gear structure parameters obtained in the step (2) is introduced into the comprehensive synthetic rigidity, obtained in the step (4), of the whole gear pair, and the gear meshing rigidity with the introduced structure parameters is obtained; and 6) establishing a six-degree-of-freedom gear dynamics model considering the structural parameter.The aviation gear dynamics modeling method considering the structural parameter.According to the aviation gear dynamics modeling method considering the structural parameter.By means of the aviation gear dynamics modeling method considering the structural parameter.Nonlinear dynamic characteristics of aviation gear transmission can be predicted more accurately, and theoretical support is provided for lightweight design of a gear transmission system.
