Actran

There is virtually no field of engineering that remains untouched by acoustic simulation technology. The reason is simple: no industry can afford to deliver a product that is too loud or does not sound right. Actran has helped transportation, aerospace and defense, machinery and consumer goods industries to meet increasingly stringent noise regulations or to guarantee that new designs are consistent with the trademark sound of the company.

Thanks to a rich library of modeling capabilities and high-performance solvers, engineers can deal with acoustic, vibration or flow-induced noise challenges in limited timeframes. A user-friendly and highly customizable graphical user interface ensures a robust and cost-efficient integration of numerical acoustic simulation into any industrial process.

Some Applications:

• Powertrain, gearbox and electric engine noise prediction

• Characterization of engine air intake and exhaust systems acoustic signature

• Side mirror and climate control aero-vibroacoustic noise analysis

• Tyre and pass-by noise assessment including acoustic treatment optimization

• Interior vehicle acoustic comfort, including fully trimmed vehicle NVH performances assessment and sound package optimization

• Transmission Loss prediction of multilayered structures considering frequency dependent acoustic treatment effects Transfer path analysis and design changes impact comparison

• Fan noise assessment considering installation effects (structure vibrations, acoustic absorption, …)

• Audio equipment integration performance assessment

• Acoustic treatment and nacelle design optimization for aircraft intake and exhaust noise

• Airframe aero-acoustic noise prediction and propagation

• Underwater noise propagation

• Prediction of vibro-acoustic fatigue due to intense random acoustic load and vibrations
