Prediction of Squeak & Rattle for robust product and production

Purpose and goal

The project has met the aim of improving the ability to predict S&R during development phases of an industrial development project. The principle has been that a robust product that is insensitive to interferences that can create S&R will provide robust production where late detected S&R problems are minimized. All work packages defined have been conducted with good results. In addition, two out of three work packages have opened-up new research questions that will further push the development of new prediction methods

Expected results and effects

The project has used different methods to improve the capability of S & R simulations. The area is by nature multidisciplinary, since the mechanisms for S&R are many and are found in different simulation disciplines. Contributing results are generated in all completed work packages through software integration modal transient analysis and tolerance analysis, reduction of iteration steps in simulation through development of a single load case replacing multiple load cases for different test tracks and finally refinements in simulation methods for S&R prediction.

Planned approach and implementation

All project partners have collaborated in the field before project started, which contributed to high efficiency. Responsibility for respective work packages was distributed among the three largest partners. All partners in the project was also connection to Chalmers Squeak and Rattle Competence Arena (SRCA), which has been a good forum for dissemination of results between partners in the project and other members of the SRCA. One of the success factors in the project has been that it was carried out by both junior and senior researchers as well as several resources from industry.
