Finite element parametric analysis system and analysis method based on database

The invention discloses a finite element parametric analysis system and an analysis method based on a database. The analysis system comprises a database, a finite element solver, and a data exchange platform. The database consists of a pretreatment database and a result database. The pretreatment database is used for a designer to input data. The data exchange platform converts the data of the pretreatment database into a finite element program code and inputs the finite element program code to the finite element solver for solution. A result file output by the finite element solver is edited by the data exchange platform and then written into the result database. The size parameter of a product can be changed by changing related parameters, and the topology of the product can be changed by increasing or decreasing data. Moreover, the requirement for the professional performance of developers is lowered, and the workload of later program modification is reduced.
