복합진동시험기를 이용한 자동차부품의 성능평가 기술

Durability of automotive parts is one of the most important factors for the vehicle performance. Vibration in the vehicle cause automotive parts failure such as short circuit, crack, loosened bolt tightening. So the evaluation of vibration property is increased in recent year. But there isn’t still the objective and standardized technology development in domestic, and moreover the requirements of the car makers and customers are more diversity. Enhancement of durability have become the necessary conditions for an automotive parts, and the durability performances under vibration have treated as the top priority. In this paper, we describe the evaluation technology for durability of automotive parts by using the environment vibration tester, which is installed and operated by Kunsan Automotive Technical innovation center.
