1. 1. Acoustic Radiation Of An Automotive Component Using Multi-Body Dynamics

   University essay from KTH/Fordonsdynamik

   Author : Shayan Aghaei; [2020]
   Keywords : NVH; Acoustic Simulation; Multibody Dynamics; Automotive;

   Abstract : An important facet of creating high-quality vehicles is to create components that are quiet and smooth under operation. In reality, however, it is challenging to measure the sound that some automotive components make under load because it requires specialist facilities and equipment which are expensive to acquire.

3. 2. Added Properties in Kaplan Turbine - a preliminary investigation

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Stina Bergström; [2016]
   Keywords : Added mass; added damping; fluid-solid interaction; acoustic coupled simulation; two way coupled simulation;

   Abstract : A preliminary investigation of the added properties called added mass, added damping and added stiffness have been performed for a Kaplan turbine. The magnitude of dimensionless numbers have been used in order to classify the interaction of the fluid and the solid. READ MORE

4. 3. Electromagnetical model of an induction motor in COMSOL Multiphysics

   University essay from KTH/Elektrisk energiomvandling

   Author : Viktor Wilow; [2014]
   Keywords : Electromagnetical model; Induction motor; Finite element method; COMSOL Multiphysics;

   Abstract : Ansys, Flux or COMSOL are examples of software-tools that can be used to study magnetic noise, caused by magnetic forces in the air-gap, in induction motors. The project team wanted to use COMSOL in this thesis. The electromagnetical domain needs to be coupled to the mechanical domain to complete the study. READ MORE

5. 4. A Wave Propagation Solver for Computational Aero-Acoustics

   University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

   Author : Elin Solberg; [2012-03-14]
   Keywords : Helmholtz equation; Lighthill’s analogy; computational aero-acoustics; finite element method; Galerkin least-squares stabilization; infinite element method; computational fluid dynamics;

   Abstract : Simulation software is increasingly replacing traditional physical testing in the process of product development, as it can in many cases reduce development times and costs. In a variety of applications, the reduction of noise is an important aspect of the product design and using methods from the field of computational aero-acoustics (CAA), the generation and propagation of sound in air may be simulated.
