摘要
根据伯金汉π定理,分析重庆菜园坝长江大桥模型的模态参数之间的关系,采用本文推导的简化方法同样得到了模态参数之间的关系。通过与伯金汉π定理的比较及试验结果的验证,证明本文所推导的简化方法的正确性。
Buckingham .9 theory is used to analyze relationship between modal parameters of Chongqing Caiyuanba Yangtze River Bridge model, also, the relationship between modal parameters are obtained via simplified method concluded in this paper. After comparison with results from Buckingham .9 theory and verification to test result, correctness of simplified method concluded in this paper is confirmed.
