Abstract
Recently we have to spread traffic system in the background of expansion ofcommunity to local area. It is useful to develop S. F. T from a view of effectiveusing of ocean space.In this paper, we suggest air spouting type actuator toreduce the unsteady fluid force of S. F. T subjected cross flow.
We researched for unsteady characteristic fluid force of S. F. T and the effectof this actuator by using parameters, void rate, oscillation rate, St. number, oscillaition frequency.
