Automotive rattle and squeak performance is an important factor affecting passenger comfort and perceived quality. In the current work, finite element simulation is developed to analyze the noise potential of adjacent interior components. The statistical “3σ” limit is adopted to assess the rattle risk at adjacent surfaces assuming a Gaussian distribution. The probability expressions about noise registration are derived for the symmetric and asymmetric tolerance zones of an initial nominal gap.Also the acoustical effects of material pairs are tested by stick-slip experiments. Results show modified polypropylene is compatible in frictional contact with itself but expresses noise when paired to adjacent components manufactured of modified acrylonitrile-butadiene-styrene terpolymer under multiple conditions.
