摘要
以常用的钝头形和近流线形两种桥梁断面为对象 ,通过在不同紊流强度的均匀格栅紊流下的节段模型风洞实验 。
Flutter is an important aerodynamic instability phenomenon.Currently,the tests and analysis of bridge flutter are mostly carried out under smooth flow,but in fact the bridges are in turbulent flow of natural wind.This paper has chosen two bridge decks in common uses as objects.Through section model wind tunnel experiment under several turbulence intensity induced by uniform grids,the effect of turbulence on bridge flutter derivatives and critical wind speed has been studied.
