More Information
Summary:The invention discloses a method for calculating dynamic meshing stiffness of gears. The method comprises the following steps: acquiring geometric parameters, material attributes and gear motion state parameters of a gear pair; calculating an overall stiffness matrix, an overall mass matrix, an overall damping matrix and an overall external load matrix; establishing a kinetic analysis finite element equation during gear meshing, and solving dynamic vibration displacements of meshing points at different moments by adopting an average acceleration method; calculating the dynamic stiffness of the two gears in the gear pair according to the dynamic vibration displacement, and obtaining the single-tooth meshing stiffness; the single-tooth meshing stiffness is superposed according to the gear pair overlap ratio to obtain the dynamic meshing stiffness; the invention further discloses a device which comprises a motion state module, a three-dimensional scanning module and a processing module. On the basis of the finit
