Simulation system and method of sheet metal punch forming technology

Abstract

The invention relates to a simulation system and method of a sheet metal punch forming technology. The system comprises a shell simulation module and a body simulation module. The shell simulation module comprises a shell stretching analysis unit, a shell springback analysis unit, a shell edge-cutting analysis unit and a shell perpendicular edge-turning analysis unit. The body simulation module comprises a body stretching analysis unit, a body springback analysis unit and a body perpendicular edge-turning analysis unit. The method includes the following steps that first, a user selects the shell simulation module or the body simulation module according to the manufacturing technology of a part; second, the shell simulation module or the body simulation module is selected, and then one or more corresponding unit simulation unit assemblies are selected; third, setting of all parameters is completed step by step according to guidance. Therefore, the simulation system and method have the advantages of simplifying simulation operation steps by using the guidance method and customizing multiple process simulation templates of parts of railway vehicles.

Description

[0001] technical field [0002] The invention relates to a simulation system and a simulation method, in particular to a simulation system and a simulation method of a sheet metal stamping forming process. Background technique [0003] The currently used DYNAFORM software has a complicated operation process and does not support one-time simulation analysis of all parts of the process, and the simulation process of the parts cannot be seamlessly integrated. [0004] The prior art scheme adopts the automatic setting module of the DYNAFORM software, which only has the single-process analysis function. Because the stamping process of all parts is generally multi-process, the existing technical solution is single-process analysis, so the multi-process analysis of parts cannot be set at one time. For example, take the lower door panel of a railway freight car as an example. The lower door panel has four simulation processes of gravity loading, forming, trimming, and springback. T...

Problems solved by technology

Since the actual stamping process of railway vehicle parts generally includes multiple processes, the existing automatic setting module does not have a customized multi-process simulation template, and can only use the single-process module for analysis. The single-process module analysis needs to be set for each process, and then completed The setting and analysis of the process is followed by the setting and analysis of the next process, and it is impossible to set and analyze the parts at one time, so the analysis process is more complicated;

[0013] 2) Since railway vehicle parts generally include multiple stamping processes, and currently there is only a single-process module in the software, it is impossible to improve the analysis efficiency of railway vehicle parts
