摘要
利用动力有限元方法,分析抗弯刚度以及支承条件对单索结构自振特性的影响,得出一部分有益的结论,可以为利用频率法测试索力以及研究索的振动特性提供参考。
By use of dynamic finite element analysis method,such factors as middle-supporting,stiffness and boundary conditions of cable which have influence on the free vibration feature of the cable are discussed.The analytical results in this paper can provide reference for the cable force test and dynamic study of the cable.
