Objectives and Approach

The objective of this project was to develop a technology platform for structural dynamic analysis that integrates fatigue analysis and acoustic radiation prediction with vibration analysis.

The prototype of the platform software is targeted at engineering workstations, using advanced user interfaces and data management techniques, with interfaces to existing CAD and FEM systems and to experimental analysis programs for vibration analysis data. The integrated platform allows interaction between designers and experimenters at an early stage in the design process. The project aimed to achieve:

• the extension of fatigue life estimation methods and their integration with vibration analysis and test
• the extension of acoustic radiation prediction techniques and their integration with vibration analysis and test
• the development of technical modelling techniques with respect to fatigue analysis and acoustic radiation prediction and their integration with geometric modelling
• the enhancement of vibration analysis techniques in view of specific requirements for fatigue analysis and acoustic radiation prediction.

Developments have been validated in conjunction with major manufacturers in the automotive industry.

Exploitation

The methodology and tools developed will have important applications in the automotive and aerospace industries and in the mechanical engineering industry in general. The following benefits are expected:

• superior products in terms of improved dynamic characteristics (reduced vibration and noise emission, improved fatigue life)
• shortened design cycles, since products with improved dynamic characteristics will require less prototype testing and trouble shooting in later phases of the design process
• higher degree of flexibility, as an improved understanding of the dynamics of the product will enable the prediction of the effects of design changes and the forecasting of the performance of variations of a new product (eg cars with different engines, gear transmissions, etc).

The results of the development will be made available as commercial products by the IT project partners.
