초록

본 논문에서는 시간영역에서 최소자승법을 이용하여 실린더 용기의 슬로시 주파수와 댐핑 계수와 함께 슬로시 모드 질량 및 슬로시 힘 작용점 높이를 시험을 통해 추정하였다. 추정한 결과가 해석 결과와 비교적 잘 일치함을 확인 할 수 있었으며 추정기법의 정확성을 파악할 수 있었다. 향후 이 기법을 이용해 액체 연료 용기의 슬로시 모델 파라미터를 추정하는데 적용할 예정이다.

The slosh natural frequencies, damping ratio, slosh mass and slosh force applying point of the liquid in cylindrical tank are estimated using the nonlinear least squares method in time domain. The estimated slosh model parameters are in good agreement with the results of the theoretical calculations for various liquid depths. Furthermore, this methodology will be applied to predict the sloshing parameters for a liquid propellant tank using ground experimental test-bed.
