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.
Actran Acoustics is the foundation module of the Actran family. It is both a standalone tool and is a pre-requisite for advanced modules like Actran VibroAcoustics, Actran AeroAcoustics, Actran for Trimmed Body, and Actran TM.
With the ability to simulate realistic modeling boundary conditions by combining dynamic, kinematic and acoustic constraints, as well as physical excitations like diffuse sound field and turbulent boundary layer, Actran AeroAcoustics can obtain accurate representation of the acoustic performance of your designs
Using Actran AeroAcoustics, the noise generated by any turbulent flow can be thoroughly predicted. Users can benefit from all features of the Actran software suite to study the interaction between the aeroacoustic noise sources and a vibrating structure, absorbent materials, or acoustic traps such as resonators.
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.
The damping pad positioning workflow has been reworked for a smoother and easier experience. Directly access the different selected and computed pad combinations without restating any new model set-up. Compare all the defined pad combinations in a single step. Apply a weight constraint and let the workflow suggest the best damping pad combination.
We have integrated the Technetics FELTMETAL™ materials family (wiremesh) in the Actran database. Easily explore which Technetics materials provide the best noise attenuation for their design by conducting acoustic simulation. Improve noise reduction performance of APU inlet/exhaust and ECS Ducting. Better control the noise in space crew compartments as well as for manufacturing machinery and heavy-duty HVAC systems.
