1003 Characteristics of Dynamic Forces due to Bending Stiffness of a Moving Elastic Body

Abstract

A nurnber of s加 dies of 且ow fields around unsteady rno 血 g airbils have examined ． In particular ， flow fields around 且exible moVing bodies attracted a great deal of attention and their elastic advantages fbr flow fields have gradually been olarified ． Howeve ろ fbr 血er research and discussion of the elastic effeCt 丘 )r flow丘elds are needed because of di缶 。ulties of 鳴 ent of bend血 g sti舳 ess ， E 正 ， which is determined by cube of a material thickness and stiflhess correspends te the resistance to cross − sectional deformation ． Therefbre ， it is impo 服 mt to 。1arify the effects of bending stif〔 hess to the flow field and dynamic fbrces ． In the present paper， we simulate the 且uid stucture interaction simulation of flow field around an elastic moving bod メ The purl 〕 ose ofthis study is to clarify the effect of bending stiflhess to the characteristics ofdynamic for ( rp acting on the elastic moving body， Key W ( ) 耐 s ：Elastic moving body ， Bending stiffrless ， CharaCteristics of dynamic fbrce ， Fluid structure interaCtion
