초록

Recently, automotive are used not only as a means of transportation, but also as a private and leisure spaces. In order to secure competitiveness in the automobile market, we must improve durability and noise/vibration technologies. The driver wants to keep quiet even if the car is used for a long time. The types of noise and vibration generated by the automotive can be divided into NVH and BSR. NVH should be reduced because it is caused by mechanical defects and aging. In this study, it was possible to accurately analyze the cause of noise and vibration, also it could identify the location, and repair that. In the future, research of an abnormal and vibrations such as NVH and BSR in automotive is needed to clearly identify.
