Actran Diffuse Sound Field (DSF) demo

Simulate the effects of a Diffuse Sound Field using MSC Actran.

What is MSC Actran?

Actran is the premier acoustics software to solve acoustics, vibro-acoustics, and aero-acoustics problems. Actran works with your existing FEA structure models from Nastran and other codes with the native interface giving you the tools to rapidly create the fluid cavity model needed and then to progress through the steps to complete your analysis.

Simulating a Diffuse Sound Field

Actran contains a whole host of functionalities to help designers and engineers predict and solve acoustics, one interesting capability, developed with a Space industry client, is the ability to simulate the effects of a diffuse sound field – such as what is experienced by the payload during a rocket launch. 

Historically this random acoustic loading has been simulated using pressure loads in a frequency response finite element analysis (FEA), but this ignores the effect of shortening wavelengths as the frequency of the sound increases, leading to conservative designs. 

This short video, delivered by our in-house MSC expert Andy Woodward will walk you through this capability in Actran and how it can be used by non-experts via a simple wizard tool.

 

 

Additional Actran Capabilities:

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 customisable to your needs. Actran, with its modular nature, can be deployed based on your applications and requirements.

  • Simulate standard and convected acoustics
  • Extract acoustic modes
  • Analyse sound field in cavities, with either modal or physical approaches
  • Model absorbing walls using impedance conditions of porous material models
  • Analyse sound radiation
  • Analyse sound propagation in ducts, intake and exhaust lines or distribution systems in buildings, aircraft, and automobiles
  • Recover vibration results from most FEA structural solvers for radiation analysis
