Experimental studies have been conducted on hydroelastic unstable vibration of a thin cylindrical weir. Five kinds of polyester test cylinders, two kinds of inner and outer tanks, and water were used in the experiment. It was found that the geometric diameter of the inner tank affects the amplitude of the unstable vibration of weir, while that of the outer tank does not. Traveling modes, in which the vibration mode rotates in the circumferential direction of the system, were observed for a thin weir when the nondimensional liquid height of the inner liquid was lo=0.75. These results may provide useful data for theoretical investigation of this kind of unstable vibration.
