New versions of ESI Group stamping simulation solution are now availableNantes 12 Oct 2000 The new 2000 versions of ESI Group's stamping simulation software have been released. ESI Group solution enables users to simulate the stamping operations from the early design stage to the whole manufacturing process. It includes PAM-QUIKSTAMP, a rapid validation tool for part and design feasibility, PAM-DIEMAKER, a dedicated software for die addendum design, as well as OPTRIS and PAM-STAMP, two comprehensive validation stamping simulation tools.
The automotive industry, car manufacturers and suppliers, but also tool and die makers, steel and aluminum companies, and press formed part producers represent the main markets for the new stamping solution.
PAM-QUIKSTAMP 2000 offers fast assessment of the formability of the part and qualitative evaluation of the die addendum. The new incremental version takes into account key parameters such as elastoplastic behaviour, friction, blankholder pressure with uncoupled membrane bending formulation. The results, obtained in a few minutes, provide guidelines for material selection, optimal cutting pattern, die addendum design, and drawbeads layout.
PAM-QUIKSTAMP 2000 offers two different approaches. The Inverse module covers a wide range of forming processes and starts from the part geometry, while the Direct module evaluates various die geometry parameters, such as, the binder surface and the die addendum including over-crown feature and die wall. The incremental method is now applied to the material using the elastic-plastic incremental material model that makes PAM-QUIKSTAMP 2000 more accurate.
Binder surface and die addendum building is a critical phase in the design of the stamping die since the changes and iterations on a large number of assumptions are often long and fastidious. To overcome this problem and reduce lead-time, PAM-DIEMAKER 2000 helps users to design and optimise stamped parts die addendum. It becomes possible to create a realistic die design in a few minutes, far upstream in a project.
PAM-DIEMAKER 2000 directly develops production run-offs areas without modifying the geometry in the CAD application. Furthermore, coupling PAM-DIEMAKER 2000 and PAM-QUIKSTAMP 2000 allows rapid assessment of part feasibility and die addendum optimisation.
OPTRIS is a virtual try-out tool for press forming simulation, well-known for its user-friendliness and its sophisticated graphical user interface. The new OPTRIS 2000 version increases the overall efficiency in the stamping simulation. Among the new capabilities, a multistage option enables users to perform a global data input of a stamping process in a single project, from gravity to springback. Other new features include macro-commands for easier data input and mapping to transfer thickness and plastic strain from one mesh to another.
PAM-STAMP 2000 offers a comprehensive stamping solution that meets the requirements of most demanding customers, like reducing costs and time-to-market for the automotive industry or enabling metal producers to validate if a part can be formed with their steel or aluminum products.
PAM-STAMP 2000 enables virtual try-out of new forming processes such as tube bending, hydroforming, flanging, and offers reliable and accurate solutions for springback calculations. PAM-STAMP 2000 enhances functionalities such as adaptive mesh refinement, trimming, gravity, drawbead control, sweeping section, etc.
Coupling PAM-STAMP 2000 with PAM-CRASH 2000 provides realistic information about the mechanical properties and "as-built" thickness distribution of a prototype in the crash performance of a vehicle.
