抄録（英）
To develop the power generation system using iron-gallium alloy, we focus on the transverse galloping vibration for a rectangular prism with a critical depth section of less than the side ratio D/H approximately equal to 0.6, and for a D-section prism which vibrates at a reduced velocity V(sub r) (=U/f(sub c)H) lower than the resonant velocity. The free vibration test using a plate spring was carried out in the water tunnel to investigate effects of the angle of attack and the vibration direction on the vibration characteristics. The vibration direction I of the prism is the same as the longitudinal direction of the prism. The vibration direction II of the prism is the same as the transverse direction to flow. We also carried out a power generation experiment using the iron-gallium alloy to investigate effects of angle of attack on energy harvesting. The D-section prism with the side ratio of 0.23 for the vibration direction I vibrates at a wide range of angle of attack in comparison with the other prisms. The maximum electric power P using a D-section prism with D/H=0.23 is 26 mW at V(sub r) = 4.15.
