Description
Technical field
The present invention relates to a kind of analogue system and emulation mode, especially relate to a kind of metal plate punching moulding process analogue system and emulation mode.
Background technology
The DYNAFORM software operation flow process adopted at present is more complicated, does not support the disposable simulation analysis of part all process steps, and the simulation process of part can't be realized seamless combination.
The prior art scheme adopts the Lookup protocol module of DYNAFORM software, and this module only possesses single procedure analysis function.Because all part punching processes are generally multiple operation, existing technical scheme is single procedure analysis, therefore the analysis of part multiple operation can't disposablely complete setting.The downside door-plate of railway freight-car of for example take is example, the downside door-plate possesses gravitational load, moulding, deburring, resilience four road emulation operations, the Lookup protocol module can't realize disposable four road emulation operations being combined into to the part punching simulation modular, therefore must, by manual intervention, can't automatically complete full procedure analysis between per pass emulation operation.
Technical Analysis method originally is as follows:
1) in the Lookup protocol module, select gravitational load (gravity), the gravitational load analytical parameters is set, carry out the gravitational load analysis;
2) after completing the gravitational load analysis, in the Lookup protocol module, be chosen to type analysis (forming), be arranged to the type analysis parameter, carry out the forming simulation analysis;
3) after completing the forming simulation analysis, in the Lookup protocol module, select deburring analysis (trimming), the deburring analytical parameters is set, carry out the deburring simulation analysis;
4) after completing the deburring simulation analysis, in the Lookup protocol module, select Springback Analysis (springback), the Springback Analysis parameter is set, carry out the resilience simulation analysis.
Adopt this Technical Analysis flow process more complicated, and the tool location of different emulation operations must reset, can't realize the automated analysis of all process steps after parameters.
2.2 the shortcoming of prior art
1) Lookup protocol module, can only realize single procedure analysis.Because the actual punching course of rolling stock part generally comprises a plurality of operations, existing Lookup protocol module does not customize the multiple operation simulation modular, can only adopt the single die piece to be analyzed, the single die block analysis need to be arranged each operation, then carry out again setting and the analysis of subsequent processing after completing this operation setting and analyzing, can't realize disposable part being arranged and analyzes, therefore the analytic process more complicated;
2) because the rolling stock part generally comprises a plurality of stamping procedures, and only has the single die piece in software at present, therefore can't improve the analysis efficiency of rolling stock part.
