| Abstract: |
| Based on loose coupling partitioned method,a wind-structure interaction numerical simulating platform of membrane structure has been established in the environment of Compaq Visual Fortran 6.5.The program is modularized,in which geometry modeling module,fluid module,structure module and data interface module keep independent each other.In geometry modeling module,the form-finding analysis program of membrane structure is adopted.In fluid analysis module,the CFD software FLUENT6.0 is adopted.In structure analysis module,the dynamic analysis program MDLFX is adopted.In data interface modul,"Thin-Plate Splines" is adopted to resolve the data transfer on coupling boundary between CFD and CSD.And the problem on dynamic mesh is effectively resolved by using algebra method and iteration method.Finally,the numerical simulation of the wind-structure interaction of one-way long-span roofs and three-dimensioned saddle-shaped membrane structure are carried out to validate the method. |
