Method and system for designing multi-core-group multi-layer ceramic dielectric capacitor model

The invention discloses a multi-core-group multilayer ceramic dielectric capacitor model design method and system, and the method comprises the steps: constructing a first model which is a geometric model of a to-be-designed capacitor model; adjusting material attribute parameters and size parameters of the first model to obtain a second model; on the basis of a mechanical environment corresponding to the capacitor model to be designed, solving a finite element model for the second model to obtain stress distribution of a contact surface of a lead and a porcelain body; based on the stress distribution of the lead and the porcelain body contact surface, obtaining a corresponding lead pin, and obtaining a to-be-designed capacitor model; the method has the beneficial effects that the designed ceramic dielectric capacitor model is combined with the corresponding mechanical environment, and related lead pins are designed through a method of continuously iteratively updating the correspondingly designed parameters,
