This invention discloses an automatic vehicle
modal extraction method and related equipment. The method includes: obtaining basic order information of the first-order torsional mode and the first-order bending mode corresponding to the basic model, and basic model displacement information of the target point, respectively, through
modal simulation analysis; obtaining
modal calculation information corresponding to multiple parametric models through
simulation analysis; calculating the similarity information between the displacement information of the parametric models corresponding to different parametric models and the displacement information of the basic model; and obtaining the torsional frequency information and torsional order information of the parametric models corresponding to the first-order torsional mode, and the bending frequency information and bending order information of the parametric models corresponding to the first-order bending mode, based on the similarity information. The method provided in this application can significantly reduce the post-
processing time of
simulation results, achieve automatic identification of modal information of parametric models, and improve simulation efficiency in the
design phase.
