MSC Actran 2020 Windows

Actran’s extensive acoustics numerical computation capabilities help engineers reduce noise and improve the sound quality of their products. It is an essential tool for analyzing noise-related problems from powertrains to sound transmission through a cockpit and fuselage. In addition to reducing noise, Actran helps engineers improve the sound of products, such as telephones, washing machines, and cameras.

Overview of MSC Actran 2020 Features

• lumped mass and springs (discrete structural elements)
• rigid porous, lumped porous, and poroelastic materials (Biot theory)
• pressure, velocity, acceleration, and admittance boundary conditions
• kinematical excitations: imposed displacements and rotations
• mechanical excitations: point load, distributed load, distributed pressure, moments
• sound propagation and absorption in a non-uniformly moving fluid
• direct frequency response analysis
• modal frequency response analysis using existing Actran, Ansys, or Nastran normal modes
• strong or weak vibroacoustic coupling
• multi-level sequence tree to avoid unnecessary re-computations
