Abstract
Nowadays, perception of automotive quality playing a crucial role in customer decision of vehicle purchase. Hence, automotive OEM’s are now working on the philosophy of “sound is quality”. Out of all the NVH issues identified in a vehicle, the ranking of BSR stands high and glove box rattle is one of the issue that is continuously observed in all customer verbatim. Specific issues like lid rattle and latch rattle are predominant and gets worse over mileage accumulation. Also minimizing BSR issues in glove box is difficult due to latch mechanism. While deciding the bumper specifications more weightage is given to efforts. The bumper is selected in a way not to increase the opening and closing efforts, but many a times the selected bumpers will not provide enough preload to glove box lid leading to rattle issues. Also, the contradictory requirements between efforts and rattle makes the scenario more difficult to fine tune the bumper specifications. In the present work, a new strategy has been introduced in the product development process to fine tune the bumper specifications to reduce the rattle issues in glove box.
