T-SIM Simulation of thermoforming

CAE.FEA.CFDadminClicks Comment
Features of T-SIM
WLF temperature dependency.
Simulates positive / negative forming with / without plug assistance.
Time dependent deformation is described by viscoelastic K-BKZ model.
Three different damping functions for a better material data fit (strain hardening).
Material database containing PE, PP, PET, PC, PMMA, etc.
Imports general 3D molds from IGES, VDA-FS via stereolithographic STL file, DXF or Patran Neutral file.
All molds movable (up to 10 tools can be used in one simulation project)
Time dependent sheet sagging included.
Friction between stretched plastic material and tools.
Heat transfer between material / tools and material / air.
User-friendly setup of technological parameters with graphic.
Windows context sensitive help, tutorials and hands-on examples.
OpenGL included, allowing dynamic image rotation, zooming and panning. This enables fast shading or wireframes and contact visualization options.
Easy, completely editable setup of T-SIM project for solver. Tight connection between initial project and result files.
Many typical thermoforming problems solved and distributed on installation CD.
Material
 
T-SIM uses time dependent, viscoelastic K-BKZ model.
Data of frequently used polymers are available in the T-SIM material database.
Any material can be tested (cooperation with IKP Stuttgart, Germany, or DatapointLabs, USA) and its data imported into T-SIM.
Solver
 
Very fast iterative multithreaded solver gets use of parallel processing on PC with more than one processor.
Upper limit of sheet elements or mold elements is limited only by PC memory available.
Fast contact analysis.
Solving a set of thermoforming problems in a batch mode. This enables automatic case study solution.
Results
 
3D cuts.
3D color maps of thickness, temperature, stress, extension.
Investigate contact between plastic material and molds.
Easy refinement of the grid in 3D areas of interest from the post-processing window.
Export results for structural analysis to Ansys, IGES, DXF, Cosmos/M or Patran files.
Output to Patran format enables structural analysis and calculation of cooling.
Interactive thickness / temperature / position information with a simple mouse click.
Export animation file to Microsoft Video Player format.
Cooling calculation.
Pre-distortion of images (option)
 
Prediction of printed image deformation.
T-SIM is able to pre-distort images for printing them on the flat sheet, so that once thermoformed, the images appear true.
Image projection manager enables projection of multiple images using various projection methods (planar, cylindrical and spherical projection).
IGES polylines can be projected, distorted / pre-distorted and exported back to IGES.
3D VRML models can be also used for image pre-distortion.
For more information about image pre-distortion, go to the reference manual.
Customer support
 
Support through Accuform representatives worldwide.
Export of internal T-SIM files for easy data exchange via Internet. This facilitates fast customer support worldwide.
Recommended hardware
 
T-SIM delivers peak performance on a multicore Intel or AMD based PC with 2 GB RAM.
T-SIM runs on Microsoft Windows 2000/XP/Vista/7/8 - 32/64 bit.
T-SIM users
 
T-SIM is used by industry leaders worldwide at Boeing, DOW, Eastman, GE, Mitsubishi, MIT, BMW, Delphi Automotive, Riley Medical, Marconi Communications, PCM, Fabri-Kal, American Standard, IPS Polymer, Illig, Kiefel, Gabler and many other thermoformers.
 
T-SIM tutorial includes examples solved using T-SIM. These examples demonstrate simulations of simple negative forming, plug assisted negative forming, positive forming, thermoforming with both tools movable and image pre-distortion.
