“…BSR is not only about occurrence but also about how frequently occurrence is obtained. 1 Weber et al, have defined about Squeak and Rattle evaluation line in two points. Firstly, the gap or contact line between the two parts and second as use of displacement output instead of Squeak and Rattle index.…”

“…For premium segment vehicles abnormal noises are not at all acceptable as such vehicles are purely built on luxury and comfort. [1][2][3] Squeak is noise generated due to sliding of mating parts over each other. Deformation of surfaces in contact stores some static energy which gets released when static friction exceeds kinetic friction, with this energy release squeak sound is produced.…”

The quality of vehicle plays an important role during the vehicle purchase. Sound quality is one of the highly ranked and commonly identified issues in automobiles. Automotive OEMs want the right-first-time design approach thus designs should be strong enough to fulfill all the criteria in terms of safety, fatigue, quality, etc. Buzz, Squeak and Rattle (BSR) are commonly classified as vehicle quality issues and marked under NVH. It is very hard to resolve BSR due to complex mechanisms and assemblies in vehicles. In this paper, the methodology is developed to reduce Rattle issues with help of shape optimization. BSR is quite unpredictable so it is hard to completely avoid it during development of overall vehicle, hence during the test run noise and its locations are marked and the focus is shifted to solving them. The methodology presented is helpful to solve the problem during the design and development phase instead of find and cure method which is currently in use. The work is limited to reducing the rattle issue in door trim and audio speaker assembly.
