利用动力有限元的方法 ,分析了单索结构的自振频率与相应振型随着单索垂度以及索结构参数的变化规律 ,得出一些有益的结论 ,可为利用频率法测试索力及研究索的振动特性提供参考。
The dynamic finite element method is used to analyze the variation law of the natural frequency and the corresponding mode shapes of single cable structure with the single cable sag and the structural parameters of the cable. Some useful conclusions are obtained, which can be used to test the cable force and Study of cable vibration characteristics provide a reference.
