Problems solved by technology
[0003] Although some existing methods can simulate and analyze the forming process more accurately, however, because there are many factors that affect the stamping forming results, how to optimize the forming parameters can only be adjusted repeatedly by engineers based on their own experience. Experience comes from deep multi-disciplinary background knowledge of mechanics, materials, mathematics, etc. and rich practical experience in production
The accumulation of this kind of experience requires a lot of time, and the result has a kind of instability, and it will waste a lot of design time and prolong the design cycle.
In addition, the default parameter values provided by existing commercial software do not take into account the characteristics of various forming parts, and cannot achieve targeted settings

The invention discloses a method for setting stamping formation parameters of a stamped part. The method comprises the steps of establishing a stamping simulation analysis database according to stamping formation simulation cases of the existing parts, wherein the database comprises geometric data of the parts and stamping dies, finite element grid data of the parts and the stamping dies, stamping process parameter data and stamping result analysis data; when new part stamping formation simulation analysis is performed, retrieving from the stamping simulation analysis database to obtain all or partial similar parts in shapes which are similar to the shape of the current part to form a similar part set, wherein the set takes part number information as unique indexes and comprises all data information of each part in the simulation analysis database; performing data mining in the similar part set, mining the setting rules of process parameters in the similar part set and generating process parameter information suitable for the formation simulation of the current new part.
Description
Technical field [0001] The invention relates to a method for setting parameters of stamping simulation forming of parts, in particular to a method for setting parameters of stamping simulation forming based on a stamping simulation database and data mining. Background technique [0002] The automobile industry is one of the pillar industries of the national economy, and about 70% of the auto body parts are formed by sheet metal stamping. Most of the sheet metal parts have the characteristics of thin material, large size, complex shape, and high surface quality, which directly lead to the development of corresponding forming molds with high design difficulties, high design costs, and long design cycles. With the rise and development of computational mathematics, mechanics and other disciplines, the accuracy of stamping forming simulation analysis continues to improve. The real process of stamping parts forming in the mold can be simulated on the computer, and then the mold can be ...
