모드 해석과 충격 가진을 이용한 차륜 진동에 대한 연구
A study on the wheel vibration using modal analysis and impact test
- 발행 : 2003.05.01
초록
When a train moves on rails, wheel and rail vibrate to produce contact noise and contact force. The former results in airborne noise and the latter transmits through bogie and excites carbody to generate structure borne noise. In this paper, wheel vibration is studied by theoretical and experimental approaches. Theoretical analysis is performed by finite element method and experimental analysis is performed by impact test. Using modal analysis and model tunning, we could have good agreement between the two approaches.
