Actran is the premier acoustics software to solve acoustics, vibro-acoustics, and aero-acoustics problems. Used by automotive manufacturers and suppliers, aerospace and defense companies, and consumer product manufacturers, Actran helps engineers better understand and improve the acoustics performance of their designs.
Some of the robust capabilities
of this module include:
• Simulate standard and convected acoustics
• Extract acoustic modes
• Analyze sound field in cavities,with either
modal or physical approaches
• Model absorbing walls using impedance
conditions of porous material models
• Analyze sound radiation
• Analyze sound propagation in ducts,
intakeandexhaustlines or distribution
in buildings,aircrafts, and automobiles
• Recover vibration results from most FEA
structural solvers for radiation analysis
Sample Applications:
• Sound radiation by vibrating structures: powertrain, engine components (oilpan, intake manifold and air
filter, valve cover, etc.), compressors, electrical motors, loudspeakers and more.
• Intake and exhaust noise, including complex mufflers and silencers.
• Analyze sound field in cavities,with either
• Air conditioning units and distribution systems (calculation of transfer matrices coefficients).
• Sound absorption inside passenger compartment of cars, trains and aircrafts.
• Sound propagation in complex media with mean flow or temperature gradient.
• Audio devices such as telephones, hearing aids or musical instruments.
