基于ANSYS模拟桥梁风致振动控制
|
摘要
文章主要介绍了ANSYS软件在某桥梁风致振动控制研究中的应用。针对桥梁风致振动,TMD作为一种机械控制措施应用在某桥梁结构上,同时采用ANSYS软件对其进行模拟。通过选用合理的单元来模拟桥梁结构、TMD控制系统和风荷载等,同时输入各单元的合理参数,最后ANSYS模拟计算出颤振临界风速,并得出相应结论为进一步深入研究提供参考。
This paper introduced the application of the ANSYS software in the wind-induced vibration control on a bridge.As a mechanical control measures,the TMD control system was used on the bridge,and then we simulated the bridge with the ANSYS software.We used the proper elements to simulate the bridge structure,the TMD system and the wind load respectively,meanwhile the reasonable parameters was chosen,finally we calculated the critical flutter wind speed and obtained a proper conclusion for the further study.
