Simulation Driven Accurate Noise Prediction for Complex Multiphysics Systems

webinar-thumbnail

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
