摘要:
风洞试验中,由于结构表面所布置的测点个数远远少于结构节点的个数,因而需要对未布置测点的屋架节点处的风压进行预测.本文采用本征正交分解法利用部分模态对部分测点风压进行了重组,并采用双线性插值和加权的本征正交分解法这两种方法对某海洋馆的屋面风压进行了预测,并对预测结果进行了比较和分析.
Abstract:
In the wind tunnel test, the pressure tab is much less than the nodes that does not distribute taps,so it is necessary to predict the wind pressure of the nodes. In this paper, we use POD to rebuild the wind pressure field and also use bilinear interpolation and proper orthogonal decomposition to predict the wind pressure of the roof of one Athletics Centre. In the end, we discussed and compared the results of the two methods.
