拱架

At first, the dynamic characteristic of gantries and main arch ribs is computed through ANSYS, which is the basis of aeroelastic model design and test condition design, and then the test results are analyzed and discussed.

首先利用ANSYS计算门式膺架和主拱肋的动力特性，据此进行气弹模型设计和试验工况设计，最后对试验结果进行分析和讨论。

The aerostatic stability analysis of the gantries and main arch ribs under wind load is accomplished by ANSYS program. Firstly, the CFD module of ANSYS is used to compute the aerostatic force coefficients of arch ribs sections. And then, the static and stability analysis of gantries and main arch ribs under several construction statuses is completed.
