Study of a Loudspeaker in a Vehicle Door

M. K. Bogdanski [1], F. Malbos [2], M. Strauss [1],
[1] Harman Becker Automotive Systems, VPDT, Straubing, Germany
[2] Harman France, VPDT, Paris, France

COMSOL Multiphysics® was used to evaluate the performance of a woofer coupled to an automotive door. Two uses cases were considered: rigid and non-rigid door structures. Using the Structural Mechanics Module, the speaker membrane displacement was computed for both cases from 20Hz to 500 ... En savoir plus

Dynamic Study of Field and Current Distribution in Multifilamentary YBCO Thin Films

F. Grilli[1], A. Lucarelli[2], G. Lüpke[2], T. Haugan[3], and P. Barnes[3]

[1]Ecole Polytechnique de Montréal, Montréal, QC, Canada
[2]College of William and Mary, Williamsburg, VA, USA
[3]Air Force Research Laboratory

We have developed a model for computing current and field distributions in multifilamentary superconducting thin films subjected to the simultaneous effects of transport ac current and applied dc field perpendicular to the sample. The model is implemented in COMSOL’s PDE module (general ... En savoir plus
