Actran for Trimmed Body

Vibro-acoustic modeling software

Advanced vibro-acoustic analysis combining Actran and MSC Nastran
Actran for Trimmed Body is a powerful tool for modeling and analyzing complex vibro-acoustic systems such as trim components. Such components are usually made of materials with high damping and strong acoustic absorption characteristics; as such they have a significant influence on the overall vibro-acoustic behavior of the structure.

Actran for Trimmed Body provides CAE engineers advanced features for mixing the best of both worlds: Actran physical model and Nastran modal model. Three types of combined models may be created:

Actran for Trimmed Body is able to merge a set of Actran models of individual trim components with a Nastran body-in-white model in order to create a fully trimmed body vibro-acoustic model.
An Actran model may be set in its real-life working environment by connecting it to an existing Nastran model (e.g. a detailed Actran model of a layered windshield may be connected to a Nastran model of the vehicle body).
A Nastran model may be enriched by including a reduced Actran model of a specific component. The Actran component is defined as a DMIG data block in the Nastran deck.
