Faster product development with improved Finite-Element simulations

11/2009The simulation of deformation processes has become an important tool for the current process optimization. It can be supported significantly by modern optical measuring methods based on digital image processing providing full-field information of 3D surface geometry, deformation and strain behavior of components under load or formed sheet metal parts. Optical measuring systems have become important tools in industrial product development cycles and in the last years and together with the finite element analysis they have significant potential for quality improvement and optimization of development time for products and production.

Finite-Element simulations

Finite-Element simulations

As part of complex process chains smooth interfaces to conventional CAD/CAM and numerical simulation systems are of particular importance.

New products and production processes are designed and optimized with numerical simulation methods. Material parameters and component deformation behavior have a significant influence on the accuracy of simulation calculations and their reliability.

ARAMIS and ARGUS are used for the validation of numerical simulations by calculating the differences between experimental measurement and FE data. The GOM Software allows the import, 3D registration and mapping of FEA results against measurement results.

A simple, fast and direct comparison of FEA data is supported by importing FEA result datasets, including ABAQUS, LS-DYNA, PAM-STAMP, AutoForm, ASCII, ...

he GOM software enables full-field comparison of FEA data sets with experimental measurements and analysis of geometry, deformation, displacements and strain values including:

  • Major, Minor and Mises strain
  • Thickness reduction
  • 3D shape/geometry comparison
  • Displacements in X, Y, Z

This full-field comparison between FEA datasets and experimental data allows easy verification of Finite-Element calculation and improvements to the Finite-Element Model, speeding up product design cycles and product development times by providing:

  • Input parameters for construction and simulation allowing a more accurate material model and prediction of material behavior.
  • First article inspection for fast and reliable prototype analysis and identification of problems.
  • Quick and reliable feedback for the construction or for optimizing simulations reducing the iteration steps in the product development cycle.
  • Quality control to accompany the series production process allowing fast troubleshooting.
  • Valuable know-how for the development of products reducing future product development times.
