This article deals with the numerical simulation methodology of electromagnetic vibrations in electrical machines. Three methodologies are compared to evaluate vibrations due to Maxwell forces in the Finite Element Analysis (FEA) software Optistruct: the direct method based on Fourier series expansion of nodal magnetic forces, and the unit rotating...
The articles studies the effect of stator magnetic wedges on the electromagnetically-induced acoustic noise and vibration of a squirrel cage induction machine. Firstly, a review of previous studies analysing the effects of magnetic wedges both on electromagnetics and vibro-acoustic domain is done. Then, simulations are performed with MANATEE® softw...
In this paper, the acoustic noise and vibrations due to Maxwell forces of a 4-pole, 12-slot, high-speed brushless DC motor (BLDC) is analysed up to 90 kRPM. The harmonic magnetic forces present in the machine are first analytically characterized, and validated with numerical simulations using MANATEE® electromagnetic and vibro-acoustic software. Th...
This article demonstrates the use of a mathematical method to efficiently discriminate and
visualize each circumferential vibration wave number involved in the yoke deflections of an electrical machine under
electromagnetic excitations. This post-processing, which can be applied on both experimental and simulation data, allows to calculate the part...
Several noise barriers made of phononic crystals (i.e. manmade composite materials with a periodic structure) have been designed over the last decade. The periodic structure of phononic crystal avoids sound propagation in a defined frequency range called Bragg band gap (i.e. waves are evanescent). This study aims at quantifying the perceptual impac...
Le concept de cristal phononique a ´ eté proposé au début des années 1990. Il s'agit de structures artificielles constituées de distributions périodiques d'inclusions insérées dans une matrice. En raison de leur structure périodique, les cristaux phononiques peuvent présenter sous certaines conditions (géométrie du réseau d'inclusions, choix des co...
