Unique capabilities packed in a powerful toolbox

The VIBES toolbox for MATLAB offers unique capabilities for Dynamic Substructuring, Transfer Path Analysis and numerical modelling. The latest scientific advancements in structural dynamics have been implemented in an esy-to-use toolbox for MATLAB. Test-based models obtained in DIRAC seamlessly integrate into the Toolbox for further processing.

The VIBES Toolbox saves you time by automating repetitive processes in simple scripts and generate plots conveniently. The toolbox creates FEM-compatible ‘super-elements’ from FRF measurements using the Virtual Point Transformation. It combines experimental component models, numerical models and operational data, accomplishing a truly hybrid approach to sound & vibration simulation. The industry-standard ASAM-ODS (ATFX) format can be used for import, managing and sharing of results.

Intuitive arithmetic and automated bookkeeping

The object-oriented workflow unlocks a wide range of Dynamic Substructuring and TPA methods, all accessible and adaptable from the command-line. Save time by automating repetitive processes in simple scripts and generate plots conveniently using intuitive commands for data selection. A unique and highly adaptable DoF-matching logic enables to combine datasets in a coherent manner, automizing the part of channel book-keeping for you.

Advanced 2D plotting

Reduce time using built-in plot functions for time and spectral data, nth-octaves, dB(A), sum levels, waterfall/Campbell diagrams and more. Quickly change plots by editing them directly through context menus within the plotting window. The toolbox includes all plotting functionality needed for advanced TPA analysis!

Toolbox for MATLAB
Powerful 3D environment

The toolbox comprises a powerful 3D environment, allowing to visualize mode shapes, work with CAD geometry and import complete measurement setups created in DIRAC. Navigate using intuitive camera controls and export mode shapes to popular video formats.

Numerical and Experimental Substructuring

The VIBES Toolbox is truly unique in its capabilities for Dynamic Substructuring. Popular numerical model reduction techniques such as Hurty/Craig-Bampton and Hintz-Herting are now available to perform true Component Mode Synthesis. RBE2 and RBE3 rigid elements are available as well, which provide the perfect “hand-shake” for coupling with experimental Virtual Point models, created using DIRAC or using the built-in possibilities of the Toolbox.
