中文摘要：
从Bernoulli—Euler理论出发，推导了吊索在一般边界条件下的自由振动频率方程和索力的解析表达式。分析了边界条件对吊索自振频率的影响，并与有限元结果进行了比较。结果表明，边界条件对吊索索力估算的影响不可忽略。
英文摘要：
According to the Bernoulli - Euler theory, the natural frequency equation and the explicit expression of the suspender tension with common boundary conditions were deduced taking into account the bending stiffness.The effect of boundary conditions＇ change on the natural frequency of suspender was analyzed. It is indicated that the effect of boundary conditions on the estimation of suspender tension can＇ t be neglected using the finite element method.
