| 摘 要： | SPAR平台装船作业和运输过程中受到的风荷载对作业的安全性有极大的影响。采用计算流体动力学方法,针对作业和极限两种工况,对桁架式SPAR平台在不同方向下的风荷载进行数值模拟,然后将数值模拟的结果和规范计算的结果进行比较,证实了CFD计算方法对复杂结构风荷载的有效性,为计算桁架式SPAR平台这类复杂结构物的风荷载提供了一个新方法。

| Abstract: | The wind loading acting on the SPAR platform during transportation and operation was very important for safety working.By use of the Computational Fluid Dynamics(CFD) method,we carried out the numerical calculation of wind loading acting on the truss SPAR platform with differents wind directions under working and extreme conditions.Then we compared numerical simulation results with the standard computation results.The research confirmed the validation of CFD method in computing the wind loading acting on the complicated structure such as SPAR platform and provided a new method to deal with this kind of wind loading problem. |
