액체 Sloshing에 의한 진동감쇠기에 관한 실험적 연구
An Experimetal Study on the Damping Characteristics of Liquid Sloshing
- 발행 : 1991.03.01
초록
This study is concerned with the fluid sloshing dampers to suppress the high vibration in the resonance and operating regions. An experimental investigation was conducted to determine the logarithmic decrement, natural frequency, tuning frequency ratio of oscillation of liquids contained in an spherical rigid container. The decay of the vibration amplitude was studied for the range of liquid filling ratio in container. The results of the investigation indicate that the sloshing motion of liquids results in an increase in the available effective damping when the filling ratio is in the region near H/R=1.3-1.6.
