| 摘 要： | ANSYS在桥梁工程中具有广泛的应用前景,并且具有开放的二次开发系统,使用方便。文章首先简要介绍了桥梁风致颤振分析的多模态参与单参数搜索M-S法,然后以VisualFortran为二次开发平台,运用M-S法编写了在AN-SYS中实现大跨度桥梁风致颤振分析的程序和相应的界面菜单程序。最后通过虎门桥的算例展示了在ANSYS中进行颤振分析的整个过程,其计算结果与大跨度桥梁空间静、动力分析程序NACS和风洞试验数据基本一致,说明了计算程序的可靠性。

| Abstract: | ANSYS is used widely in bridge engineering with opened second-development system.The Multi-mode Par-ticipating and Single Parameter searching method(M-S method)is introduced briefly at first,and then the according pro-gram,which is used to implement wind-induced flutter analysis of long-span bridge using visual fortran based on M-S method in ANSYS,is developed by the authors of the paper.The example of HUMEN Suspension Bridge illustrates the whole procedure of wind-induced flutter analysis in ANSYS,the result shows according with result of wind tunnel test and the program NACS developed by authors. |
