Abstract
<div>In order to improve the squeak and rattle (S&R) performance level of
automotive interiors, the contact nonlinear characteristics of structural
components need to be considered when performing interior noise analysis. The
finite element model of S&R analysis of the interior assembly is built, and
the time-domain vibration characteristics of the contact points between the
interior panels are analyzed by applying external forced excitation. The
interaction force between contact points is obtained according to the contact
equivalent model between interior materials. The external excitation and
internal interaction force are analyzed as the total excitation to obtain the
response results. Through experimental verification, compared with the S&R
performance division method, the analysis results are consistent with the test
results. Based on this model, S&R risk optimization is carried out, and the
risk level is significantly reduced. The research shows that the level of
S&R performance can be accurately predicted by considering the nonlinear
contact problem of the contact point in the S&R analysis of interior
assembly, which has important guiding significance for the forward development
and optimization design of automobile S&R performance.</div>
