Abstract

The embodiment of the invention discloses a modal simulation method, a device a computing device and a storage medium for a vehicle generator stator. The modal simulation method establishes a 3D modelof the stator core and determines a core characteristic model parameter associated with the modal simulation result. A first independent model parameter is selected from the stator core feature modelparameters. The theoretical value and the actual value are then assigned to the first independent model parameter and the simulated modal parameters are compared with the results of the experimentalmodal parameters. When the simulation result is inconsistent with the experimental modal result, the first independent model parameter given the theoretical value is corrected. The modal simulation isperformed again, so that the modal simulation results of the stator core are consistent with the experimental results. Thereby the theoretical value of the first independent model parameter of the stator core is corrected and the value of the stator core parameters can be more consistent with the actual working conditions.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of modal simulation, and in particular to a modal simulation method, device, computing device and storage medium for a stator of a vehicle generator. Background technique [0002] With the popularization of automobiles in human society, automobile noise has attracted more and more attention, and a large part of the source of automobile noise comes from the generator in the automobile, and a large part of the noise of the automobile generator comes from the stator core and winding. Vibration under the excitation of electromagnetic force, in order to better reduce the noise of the automobile generator, it is necessary to reduce the stator noise as much as possible. [0003] In the design process of automobile generators, it is often necessary to simulate the modal of the stator to guide the design of the stator of the generator. [0004] However, the existing stator modal simulation ...
