Free Field Technologies, the Belgium arm of MSC Software that is now part of Hexagon Manufacturing Intelligence, a global engineering software company, announced the Actran 2020 design and simulation software suite comprising new acoustic, vibro-acoustic and aero-acoustic technologies that enable manufacturers to build more accurate noise prediction models of their designs, with optimizations into their processes.

Aircraft operators face growing restrictions on noisy aircraft and more stringent International Civil Aviation Organization (ICAO) noise management regulations. Reducing noise has become a business priority due to landing fees, flight curfews, or fleet being excluded from some airports. This is driving aerospace innovation, with engine technology paramount for effective aircraft noise reduction.

At the intake, engine noise is dependent on both the axial flow through the turbo fan and the associated swirl, but the combined effect on noise propagation was historically challenging to model. Actran’s aircraft engine noise prediction now automatically accounts for the mean flow swirl component in acoustic duct modes excitation, which avoids mismatches between nacelle inlet flow and boundary conditions. The more accurate simulation enables engineers to understand how design changes such as shortening the nacelle affect noise emissions so they can optimize the placement of acoustic treatments.

At the exhaust, simulating the indirect combustion noise of aircraft engines was rarely feasible due to the cost of computation. The Cumpsty and Marble compact model is now implemented in Actran, applying inexpensive modeling to assess indirect combustion noise in a turbomachine. Recently developed and validated against measurements together with Safran Helicopters Engines, the model enables manufacturers to predict the combustion noise emitted in engines.

The forthcoming ISO 360-1 standard reflects growing pressure to reduce automotive pass-by noise, with tyre noise expected to contribute 60% by 2024. A new dedicated noise assessment utility in Actran maps rotating tyre time domain vibrations from frequently used tools such as Abaqus onto a tyre-deformed mesh. This model is transposed into the frequency domain to predict tyre noise radiation in-situ so that acoustic mitigation solutions can be optimized accurately within a single acoustic engineering environment.
Decision making is also improved for Noise, Vibration, and Harshness (NVH) engineering workflows. Test results required by metrology and quality teams are now automatically produced for virtual tests in accordance with standard acoustic test procedures for power radiation and automotive pass-by noise measurements including ISO 3744, ISO 3745, SAE J1074 and IEC 61672-1.

Electric vehicles manufacturers can now effectively address interior noise from electric motors, which is very pronounced at mid and high frequencies using Actran SEA. Its meshless simulation engine simulates large vibro-acoustic systems based on existing (low frequency) finite element models in MSC Nastran. Acoustic engineers can now model a whole vehicle including multi-layer poro-elastic materials at mid to high frequencies and optimize the insulation, damping and absorption effects of acoustic treatments within weight and cost constraints.

Actran 2020 is designed to make model set-up and definition more efficient with a reorganized analysis tree, components and boundary conditions categories and a new layout and native unit conversion system offering further productivity enhancements. Actran 2020 is now available.

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.

Actran provides a rich library of material models, a complete element library that includes infinite elements, high performance solvers to solve large size problems and a user-friendly GUI that is highly customizable to your needs. Actran, with its modular nature, can be deployed based on your applications and requirements.

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 and Actran TM.
