Optimization design method, device and equipment of side wall outer plate and medium

The embodiment of the invention provides an optimization design method and device for a side wall outer plate, equipment and a medium. The optimization design method of the side body outer plates comprises the steps of obtaining structure models of two adjacent side body outer plates to be optimized; discretizing the structure model of the to-be-optimized side wall outer panel to obtain a finite element model; performing model assembly on the two finite element models according to the assembly process parameters and the assembly position relation to obtain an assembly model; performing thermal deformation simulation on the assembled model according to a material thermal expansion coefficient and baking varnish process parameters to obtain a thermal expansion model; and identifying a contact area of the two finite element models in the thermal expansion model, and optimizing the structure models of the two to-be-optimized side wall outer plates based on the contact area.
