Abstract

The embodiment of the invention discloses a modality simulation method and device of a vehicle-used generator, computing equipment and a storage medium. A three-dimensional model of the generator is established, and the three-dimensional model includes a three-dimensional model of a stator core; core feature model parameters associated with modality simulation results are determined; first independent model parameters which are mutually independent are selected from the core feature model parameters, and then theoretical values and actual values are assigned to the first independent model parameters; through comparing results of modality parameters of simulation and test modality parameters, the first independent model parameters with the assigned theoretical values are corrected when thesimulation results are inconsistent with the test modality results; and the modality simulation results of the stator core are enabled to be consistent with the test results, thus the theoretical values of the first independent model parameters of the stator core are corrected, and an equivalent model conforming to actual generator modality is established on the basis thereof; and increasing of acomplete-machine development level of the generator is facilitated through modality simulation on the equivalent model.

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 of a vehicle generator. Background technique [0002] With the popularization of automobiles in human society, people pay more and more attention to automobile noise, and a large part of the source of automobile noise comes from the generator in the automobile. [0003] A large part of the noise of the generator comes from the vibration noise of the generator under the excitation of electromagnetic force. In the design process of the automobile generator, in order to reduce the noise of the generator, it is necessary to simulate the mode of the generator to guide the generator the design of. [0004] However, the existing modal simulation methods are often a theoretical simulation, and the theoretical simulation results have not been verified by actual test results, or, ...
