In this paper, the elastic-plastic finite element numerical calculation and parametric design method are applied. The parameterized design of the finite element calculation of the structure of the electronic equipment connector is carried out, and the parametric finite element simulation system of the connector structure is developed based on the ANSYS platform. The principle and method of the parametric design system PDA and the parametric library tool PDS. On this basis, the parametric design of shipboard electronic equipment structural parts and the realization method of building a database are expounded, and specific application examples are given. to realize the spatial modeling of the circuit. Using this general program, the circuit space model can be easily modified without re-modeling with the interface.
