Simulation Driven Accurate Noise Prediction for Complex Multiphysics Systems

Determination of noise, vibration and harshness (NVH) for systems with complex coupled physics presents many acoustics design challenges. Accurate prediction of noise and sound propagation plays a pivotal role in the efficient design of products across industries and applications. Simulation has become a very cost-effective approach for solving different wave propagation problems in a coupled way by solving fluid and structural domains simultaneously or in a sequential, uncoupled way by performing fluid/electromagnetic analysis followed by structural and then acoustics analysis.

ANSYS solutions are being widely used to solve aero-vibro, electromagnetic-vibro and MEMS-vibro coupling problems. Join us for this webinar to learn about ANSYS Mechanical solutions for acoustic modeling and simulation. In this session we will discuss the following topics:

  • Coupling between flow pressure (using computational fluid dynamics) and vibro-acoustics (using finite element methods)
  • Coupling between electromagnetic forces and vibro-acoustics
  • Transfer of loading data from the time domain to the frequency domain
  • Application example: prediction of windshield noise
  • Application example: prediction of electric motor noise
  • Far-field post processing
