Improved dynamical models; compensation for local non linearities

Reference number
Coordinator SAAB Aktiebolag - Saab Aerosystems
Funding from Vinnova SEK 3 900 000
Project duration April 2011 - June 2013
Status Completed

Purpose and goal

Tha aim has been to establish a knowledge base and develop methods for calibration of locally non linear dynamic models and to educate two PhD students; one at Linnaeus University in Växjö and one at Chalmers in Göteborg. The goals have been to acomplish good quality research for publication such that the PhD students would be able to become Licentiate of Engineering and develop methods for localization, using measurement data, of the physical reasons for the non linear structural behavior enabling improvement of the models.

Results and expected effects

The project resulted in methodology for localization (location and type) of the non linearities within structures that are to a great portion linear. The methodology needs somewhat more development and industrial implementation; a major step has been taken during this project. Furthermore, the two PhD students are expected to become Licentiates of Engineering in the end of 2013.

Approach and implementation

The Project has been running, for two and a half years, as a PhD student project. One PhD student at Linnaeus University in Växjö and one at Chalmers have, together with their supervisors, been involved in the project. Personnel from Saab has been engaged in the manufacturing of test structures and in vibrational testing.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
