摘要
本文利用D’Alembert原理,对索在弹性支撑条件下的自由振动频率方程和索力的解析表达式进行了推导,并与有限元结果进行了比较.结果表明,利用振动法测索力时,考虑索弹性支撑条件,可运用本文给出的索力公式进行索力估算.
In this paper, according to D＇Alembert principle, the natural frequency equation and the explicit expression of the cable tension with elastic support conditions are deduced, and compared with finite element results. The results show that the tension of cable measurement by vibration method considering the elastic support conditions of cable, the formula to cable tension is given in this paper and it can be used to calculate the tension of cable.
