Computational Aspects of Structural Acoustics and Vibration
June 19, 2006 — June 23, 2006
Coordinators:
- Goran Sandberg (Lund University, Lund, Sweden)
- Roger Ohayon (Conserv. Nat. Arts & Metiers, Paris Cedex 03 , France)
The event is part of the program elaborated for the European Atelier for Engineering and Computational Sciences (EUA4X – Marie Curie program). Some of the lectures will be also available on line.

Scope
Fluid-Structure Interaction is a powerful tool for investigating acoustic and structural-acoustic problems in many sectors of industry in the building industry regarding room acoustics, in the car industry and aeronautical industry for optimizing structural components with regard to vibrations characteristics etc. It is on the verge of becoming a common tool for noise characterization and design for optimizing structural properties and geometries in order to accomplish a desired acoustic environment.
The course starts in the field of computational mechanics, and then moves into the field of formulations of multiphysics and multiscale and covers the following items:
Structural dynamics
Various formulations for fluid-structure interaction, benefits and drawbacks, for
– cavities
– external fluid
Modelling issues
– validity of various formulations with regards to the physics
Source terms e.g.
– vibrating equipment
Application within the automotive industry and building acoustics.
As a vehicle for both the theoretical discussion and modelling issues realistic examples will be used; two rooms with an intersecting flexible wall that also contains a cavity. Hands on work on computers to model and solve problems related to the course will be issued.
The course is addressed to graduate level, PhD students and young researchers interested in structural dynamics, vibrations and acoustics. It is also suitable for industrial researchers in mechanical, aeronautical and civil engineering with a professional interest in structural dynamics, vibrations and acoustics or involved in questions regarding noise characterization and reduction in building, car, plane, space, train, industries by means of computer simulations. The course also should be of interest to researchers in applied mathematics wishing to learn about modern developments in the modelling of mechanical and civil engineering structures.
A basic knowledge of mechanics, applied mathematics and numerical methods is required.
