Actran Acoustics

Actran Acoustics is the gold standard in Acoustic Simulation software for engineering teams. As a result, engineers worldwide rely on it to analyze and reduce noise across automotive, aerospace, and industrial applications. Therefore, leading manufacturers trust Actran Acoustics to deliver reliable simulation results on every project.

What is Actran Acoustics?

Protecting people from noise and vibration, as well as ensuring acoustic comfort in the operation of technical systems are among the important tasks in the development of new products in various industrial sectors. In addition, ensuring the strength and durability of structural elements and the operation of electronic systems also requires acoustic load analysis. Furthermore, computational methods of acoustic analysis are actively used by designers to assess the influence of design parameters on acoustic characteristics and for the effective use of sound-absorbing materials. Therefore, Actran Acoustics is the ideal solution for engineers who need accurate, fast acoustic simulation results.

ACTRAN METHODS

Typical applications of Actran are modeling the internal and external acoustic fields of various transportation systems. For example, simulation of noise in the undercarriage of a car and noise impact on the driver and passengers in the cabin, simulation of acoustic characteristics of the exhaust system of an internal combustion engine, analysis of noise in the cabin of an aircraft from various external influences, research and selection of characteristics and design of sound-absorbing devices and coatings, and so on. Besides, it is possible to conduct acoustic analysis of the characteristics of consumer goods, such as cell phone speakers, freestanding speaker systems, musical instruments, other types of sound reproducing devices, etc.

The software package includes modules for solving the following classes of problems:

Acoustics and vibroacoustics in the frequency and time domain;
Aeroacoustics with direct calculation of noise sources;
Aeroacoustics with noise generation in Actran;
Aeroacoustics of GTEs;
Specialized modules, including profile and fan noise generation, vibroacoustics analysis based on Green’s theorem, and “film” vibroacoustics analysis based on vibration waveforms of vibrating surfaces.

Complex calculation in Actran
Actran provides several highly efficient algorithms for solving problems. These algorithms provide high speed solutions to acoustic problems, which in most cases require significant machine resources.

Actran’s tight integration with MSC Nastran, Adams, scFlow, and Dytran allows you to leverage the strengths of each product. For example, the analysis of structural vibrations can be performed using MSC Nastran (the accuracy and speed of such calculations is generally recognized), and the simulation of sound propagation in the environment – using Actran (the product is optimized for solving exactly such problems).

In short, MSC Actran covers a comprehensive range of acoustic simulation scenarios. The wide range of tasks to be solved allows the use of Actran in the development of promising models of automotive, aviation, space, railway equipment, consumer goods, electronics, industrial systems of mining and processing of minerals, etc. Moreover, the software integrates seamlessly with existing engineering workflows, allowing your team to identify and resolve acoustic issues earlier in the design cycle. Additionally, GloBAS Engineering provides full technical support and training for Actran users.
