General-purpose acoustic analysis system "Actran" *Free case study collection available!

Sound simulation in 3D detailed models is now possible! Analyze radiated sound and noise generated from various structures! Large-scale acoustic analysis is also possible.

"Actran" is a general-purpose tool for acoustic analysis. By selecting the optimal solver (finite element method, finite volume method, statistical energy analysis) according to the target, it enables analysis tailored to objectives (accuracy, cost) and development phases. It also allows for understanding the sound propagation mechanism through animation and auditory prediction using sound playback functionality. 【Features】 ■ Supports both structural vibration sound and fluid sound ■ Coupled calculations between flow-structural vibration-sound ■ Compatible with not only FEM (finite element method) but also SEA (statistical energy analysis) ■ Includes thermal and simplified CFD functions, considering the effects of background differences on sound propagation. ■ Large-scale acoustic analysis with hundreds of millions of degrees of freedom, essential for high-frequency analysis beyond the audible range ■ Supports three fluid sound sources (Lighthill, Mohring, pressure fluctuations on structural surfaces) ■ Supports random sound fields. Acoustic transmission loss analysis using diffuse boundary conditions is also possible. ■ Capable of both frequency response and time history response analysis ■ Analysis using experimental data is also possible ■ Optimization through automatic continuous execution of parameter studies *For more details, please refer to the PDF materials or feel free to contact us.
