摘要:
根据实际悬挂缆索的受力情况推导了缆索悬挂曲线满足的微分方程; 采用数值方法分别计算了在不同情况下考虑抗弯刚度时缆索的悬挂线形,并与采用悬链线理论计算的结果进行了对比。结果表明:在确定的物理特性下,缆索的悬挂线形与缆索的抗弯刚度和无应力长度有关; 无应力长度越长时,缆索的悬挂线形越接近悬链线理论的计算结果。所得的计算结果可以为实际缆索结构精确计算模型的建立提供参考。
Abstract:
Authors derived a set of differential equations for real suspended cables according to the force conditions. Then, authors calculated the suspended curve-shape of cables by using numerical method under different conditions and compared them with the calculation results of catenarian theory. Results show that suspended curve-shape of cable is related to flexural rigidity and unstressed length of cable in determined physical characteristic, when unstressed length of cable is longer, the suspended curve-shape of cable and the catenarian curve are more similar. The calculation result can provide reference for building accurate calculation model of real cable structures.
