Abstract

The invention belongs to the technical field of automobiles, and discloses an automobile damping plate simulation modeling method, device and equipment and a storage medium, and the method comprises the steps: determining a damping plate boundary line according to an automobile damping plate image; generating a damping plate wireframe according to the damping plate boundary line, and determining a damping plate target surface according to the damping plate wireframe; dispersing the target surface of the damping plate into a plurality of surface units according to a preset finite element analysis algorithm, and constructing a three-dimensional body unit according to the surface units; and modeling the three-dimensional body unit according to a preset unit node fusion algorithm to obtain a target damping plate simulation model. According to the method, real shapes, thicknesses and attributes of damping plates such as boundary lines and wireframes of the damping plates are fully considered, the target damping plate simulation model obtained by using the preset finite element analysis algorithm and the preset unit node fusion algorithm can truly reflect the boundary and thickness of the damping plates, and errors are smaller; the simulation precision and credibility of the vehicle body model containing the damping plate structure are improved, and errors of simulation vehicle body analysis are reduced.

Description

Technical field [0001] The present invention relates to the field of automotive technology, and more particularly to an automobile damping plate simulation modeling method, apparatus, device, and storage medium. Background technique [0002] At present, for damping, sound insulation, and rigidity, the current car body sheet metal and door cover system can often be plastic parts such as damping plates and epoxy plates, especially in the floor, before Board, rear wheel cover, lateral outer plate, and door exterior plate, damping plate, and epoxy supplement plate mainly act as a role of damping and sound insulation. However, when the simulation is analyzed, the body modal, stiffness, and local mounting point, the damping plate and the epoxy replenishment plate will cause an error in modal analysis, causing not in calculating stiffness, especially local stiffness. accurate. [0003] The above content is only used to assist in understanding the technical solution of the present invent...
