Vehicle body beam structure optimization method, device and equipment and storage medium

The invention relates to the technical field of automobile structure optimization, and discloses an automobile body beam structure optimization method, device and equipment and a storage medium, and the method comprises the steps: converting stress data into equivalent section parameters according to a two-dimensional section model of an automobile body beam structure; optimizing the equivalent section parameters based on the two-dimensional section model to obtain section design parameters; and synchronizing the section design parameters to the three-dimensional whole vehicle finite element model for checking calculation, and determining optimization design parameters. Compared with the situation that a traditional vehicle body beam structure optimization mode is complex in calculation, prone to errors and time-consuming and labor-consuming, the method has the advantages that the vehicle body beam structure is reduced into the two-dimensional section model, and then stress data of the three-dimensional whole
