Vacuum Forming Simulation Program T-SIM

By adopting a viscoelastic model of the integral type, accurate analysis of sheet sag during drawdown and cooling after molding is achieved.

We flexibly reproduce the increasingly diverse vacuum forming processes, including the specification of clamp positions, temperature and thickness distribution of the sheet, friction and heat transfer between the mold and the sheet, timing of vacuum and pressure air, and the shape of the assist plug. We automatically calculate the optimal initial sheet temperature settings to achieve a uniform thickness distribution.

basic information

**Features** - Import mold shapes from STL, DXF, Patran, and VRML files. - Material slip due to differences in mold materials is reproduced based on the friction coefficient. - The material model employs the integral-type viscoelastic models K-BKZ and Leonov. - Accurately simulates time dependency and large deformations, reproducing draping of sheets and parisons with high precision. - Physical property data for major materials is already registered, allowing for immediate analysis. - Three different damping functions that accommodate strain hardening. - Adopts the WLF temperature dependency model. - Achieves short computation times through a multi-threaded solver and batch analysis system compatible with 64-bit parallel processors. - Displays post-molding thickness, temperature, stress, and elongation rate in detailed graphs using a 3D color scale and arbitrary cut lines. - Predicts molding defects and their risks through contact conditions between the mold and sheet, highlighting large deformations of the sheet, and providing weight calculation functions for arbitrary parts. - Analysis results can be exported to ANSYS, IGES, DXF, Cosmos/M, Patran, and LS-Dyna files for structural analysis.
