Modelling Vibro Acoustics and Shock

Modelling Vibro-Acoustics and Shock

A workshop on the State of the Art

Application of finite element analysis (FEA), boundary element analysis, or computational fluid dynamics simulation techniques to product design is well established in many industry sectors for fundamental static, thermal and dynamic environments.


There are a number of methods reported with respect to Vibro-Acoustics and Shock excitation, classical methods, FEA, boundary elements and Statistical Energy Methods.

Is there a coherent summary of the methods and benchmarks that illustrate and verify the application of these techniques such that the methods can be as routinely applied as a design tool?


This workshop included:

  • Presentations from a variety of industry sectors describing the application of Vibro-Acoustic analysis and modelling techniques to product design.
  • Presentations by vendors of typical methods available for modelling and analysis of Vibro-Acoustic and shock environments.

  • How current Vibro-Acoustics and Shock simulation tools have been applied in industry to address product design with respect to these environments.
  • Are Vibro-Acoustics and Shock modelling and analysis techniques mature enough to influence product design?
  • What is required to improve the effective application of Vibro-Acoustic s and Shock simulation techniques by industry?

Who Attended?

  • Managers and engineers responsible or involved in the design and analysis of their company’s products.
  • Academics and researchers involved in teaching, standards and benchmarking of simulation techniques.

The workshop included presentations on Vibro Acoustics and Shock simulation techniques from users and vendors. There was opportunity to discuss the maturity of Vibro Acoustics and Shock modelling and analyses tools and identify the scope of future developments to encourage the effective application of the techniques to product design for Vibro-Acoustics and Shock excitation.
