Abstract [en]

Squeak and Rattle are nonstationary sounds that imply quality deficiency in premium cars. In order to enhance prediction and verification capabilities of squeak and rattle problems upfront in product development phases, robust and accurate virtual models are required. In this research, a modelling approach is employed to simulate the nonlinear response of impact events from a rattle-producing machine by finite element analysis. The model comprises nonlinear contact interactions to capture the system response at impact events and is correlated versus experimental data considering the modal and time domain response. A sensitivity study is performed on the parameters of the contact model. System response is formulated in the form of impact kinematic and kinetic components, which are well correlated with rattle sounds in impact events. The parameters with high impact factor are identified. These results can be used to estimate the response with higher accuracy and enhance rattle event prediction capability.
