Simulate and improve the acoustic behavior of your products to reduce noise and optimize their sound quality.
Identify noise levels early in the design process to meet constantly changing and stringent noise regulations.
Understand and implement key insights into acoustic phenomena, to improve the acoustic performance of products.
Complete solution for noise and acoustics, providing accuracy, speed and ease-of-use for acoustics, vibro-acoustics and aeroacoustics problems across the full frequency range.
Actran enables you to push the boundaries of acoustic design, by reducing product development time and gathering increased insights into how to improve product performance. Its advanced simulation tools make predicting acoustic issues a seamless task.
Reinvent your acoustic analysis and modelling operations, ranging from aircraft engine noise and powertrain noise to trim packages and sound barriers. Actran’s intuitive graphical user interface facilitates the modelling of acoustics across the sound spectrum, and its state-of-the-art solvers provide answers fast, for more design iterations at a lower cost.
The newest version introduces a new compressed way to store reduced impedance matrices (RIM) for 3D acoustic trim analysis. Drastically reduce the size of those matrices and reduce computational time due to fewer I/O operations. Fine-tune the accuracy with the CRIM_TOLERANCE keyword. A higher tolerance will select more modes, leading to more accuracy but less compression.
3D meshed trims can be easily converted to 1D analytical trims. Reach higher frequencies at a lower cost in terms of runtime and memory consumption. Quickly access trim performance indicators like transmission loss. Reuse the existing 3D trims for building up a SEA model (only supporting 1D trim definitions).
Easily set up an acoustic radiation model starting from experimental vibration data (surface acceleration, velocities or displacements). Avoid complex structural dynamics modelling and rely on experimental data to assess the noise emission. Conduct a structure-borne transfer path analysis with a hybrid approach mixing experimental and computational results.
