MSC Actran 2020

Introduction to MSC Actran 2020

Overview

MSC Actran 2020 is a general-purpose finite element program designed for modelling sound propagation, transmission, and absorption in acoustic, vibro-acoustic, or aero-acoustic contexts. It provides engineers with powerful tools to analyze noise-related issues and improve the sound quality of their products.

Features

• Lumped mass and springs for discrete structural elements
• Various types of materials such as rigid porous, lumped porous, and poro-elastic materials based on Biot theory
• Different boundary conditions including pressure, velocity, acceleration, and admittance
• Kinematical excitations like imposed displacements and rotations
• Mechanical excitations such as point load, distributed load, distributed pressure, and moments
• Analysis of sound propagation and absorption in non-uniformly moving fluids
• Direct frequency response analysis
• Modal frequency response analysis using Actran, Ansys, or Nastran normal modes
• Vibro-acoustic coupling options for strong or weak coupling
• Multi-level sequence tree to avoid unnecessary re-computations

Use Cases

Actran is a vital tool for engineers working on noise-related problems in various industries. It can be used for analyzing noise issues in powertrains, sound transmission through cockpits and fuselages, and improving the sound quality of products like telephones, washing machines, and cameras.
