댐퍼 스프링의 동적 히스테리시스 저감이 터빈 진동 개선에 미치는 영향에 관한 연구

In this thesis, we explain developing processes for torsional damper of torque converter to improve turbine oscillation at passenger car. Turbine oscillation is one of the major NVH issues of the vehicle because it is directly connected to the durability and ride comfort. So, we propose a way to solve this problem by reducing the hysteresis torque of damper spring. And also, predicts vibration transmissibility of the improved design using simulation analysis.
