摘要
对钱塘江三桥 1 5号斜拉索进行了振动及被动控制测试 ,用频响函数非线性拟合方法得到了斜拉索的振动频率及等效模态阻尼比。依据测试分析结果提出了斜拉桥拉索的振动特性及被动油阻尼器控制存在的不足。
The field tests of the vibration and passive control of cable in Qiangjiang were carried out.The vibration frequencies and equivalent modal damping ratio of cable were obtained by nonlinear fitness method of frequency response functions.The vibration characteristics of cable and deficiency of oil dampers control were presented according to the field test results.
