| 摘 要： | 本文以风载下桥梁的抖振引起的拉索振动为研究对象,首先通过AN SY S进行实桥建模,用接近实际的单元来模拟拉索,并编程对拉索位于桥面端施以简谐位移激励,得到拉索在桥梁竖向抖振下引起的拉索最大振幅,最后通过对拉索施加阻尼器,得到油压阻尼器即能起到很好的抑振效果.

| Abstract: | When the wind blow across the bridge,it may cause the buffeting of the bridge.This paper is concerned mainly with the vibrations of the cable which caused by the buffeting of the cable-stayed bridge.First,the cable-stayed bridge model in ANSYS is built and then the cable using an appropriate element is simulated,including programming and apply different cable with different time-varying displacement at the support which lies to the bridge,the maximal swing of each cable is obtained.At last,the damper is applied to some of the cable which have a biggish swing.The results of the vibration reductions are satisfactory. |
