| 摘 要： | 参照经典流体力学流动相似准则的推导方法,针对大跨度屋盖详细推导了结构动力相似准则,并对各相似准则进行了细致的讨论及取舍,总结出大跨度屋盖气弹模型风洞试验需要满足的相似条件.同时本文特别论证了大跨度屋盖气弹模型风洞试验可以不模拟傅罗德数相似准则,这将在很大程度上简化模型的设计和制作.最后以具体的应用实例进行了验证.

| Abstract: | Refering to the deducing method of similarity criterion in classical fluid mechanics,the structural dynamics similarity criterion of large span roofs is detailedly deduced in the paper.Each similarity criterion is discussed and selected.The similarity criterion for aeroelastic model wind tunnel test of large span roofs is summarized.The paper specially demonstrates that the Froud similarity criterion is not necessary for such test,which will make the design and fabrication of the model greatly simplified.The theory is proved by an application example. |
