초록
A vertical planar motion mechanism(VPMM) test was used to increase the prediction accuracy for the maneuverability of anunderwater glider model. To improve the accuracy of the linear hydrodynamic coefficients, the analysis techniques of a pure heave test and purepitch test were developed and confirmed. In this study, the added mass and damping coefficient were measured using a VPMM test. The VPMMequipment provided pure heaving and pitching motions to the underwater glider model and acquired the forces and moments using load cells. Asa result, the hydrodynamic coefficients of the underwater glider could be acquired after a Fourier analysis of the forces and moments. Finally, amotion control simulation was performed for the glider control system, and the results are presented.
