Engine Mount Snubber의 실내소음에 미치는 영향에 관한 연구

This paper is looking for interior noise contribution of engine mount snubber shape. Mount snubber is very important for durability. Furthermore, it has not been concerned about NVH performance according to snubber shape. Actually, engine mount snubber is contacting with mount bracket. We conduct several kinds of test to look over how mount snubber can effect on interior noise. Snubber shape and gap between snubber and mount bracket can deteriorate interior noise booming and sound quality as well. The smaller snubber shape, the better interior noise we got. However, still we need snubber due to durability. Therefore, we need to optimize snubber shape for both durability and NVH performance. It means it is necessary to compromise between them during the engine mount snubber design stage.
