Squeak & Rattle simulation at Volvo Car Corporation using the E-LINE™ method

Paper i proceeding, 2013

A new method for Squeak&Rattle simulation and a new approach for correlating the simulation results to real Squeak&Rattle issues have been presented in the SAE paper 2012-01-1553. This paper focuses on the integration of this new simulation approach into an existing virtual design process. Both the technical aspect of the integration and also the organizational integration will be shown. The technical aspect can be split into a pre- and postprocessing part. On the preprocessing side the improvement of the FE model and the load definition using test data will be described. On the postprocessing side the stick-slip test data base and the tolerance analysis will be linked to the E-LINE™ program in order to use these data as criteria for the Squeak&Rattle assessment. By taking the capability of this new simulation approach into account the organizational integration is presented where the E-LINE™ method becomes an efficient tool to support the daily design work within both interior and exterior applications.
