强耦合法在膜结构风振流固耦合分析中的程序实现与应用

研究强耦合整体方法在膜结构风振流固耦合效应分析中的程序实现与应用。基于强耦合整体式方程，介绍了采用Fortran语言编写膜结构流固耦合效应计算程序的实现过程，以及程序实现中需要的数值计算方法。对计算程序中的重要求解步骤进行了分析，介绍了相应程序的实现过程。最后将强耦合整体方法计算程序应用于典型膜结构的风振流固耦合计算中，得到了结构在不同风向角下考虑和不考虑耦合效应时的风压系数，其结果与已有风洞试验结果基本一致。同时计算了膜结构的风振响应和周围流场的分布。结果证明提出的强耦合整体方法程序适用于计算膜结构风振中的流固耦合效应，结果正确可靠

Implementation and application of strongly coupling method in fluid-structure interaction analysis on wind-induced vibration of membrane structures

Based on strongly coupled simultaneous equations,the programming of calculating fluid-structure interaction in wind-induced vibration of membrane structures was implemented by using Fortran language and the numerical methods needed in the program were presented.Then the program was applied in the calculation of fluid-structure interaction in wind-induced vibration of a typical membrane structure.Wind pressure coefficients were computed with considering and without considering interaction effects under diffe...
