本文提出了一种小应变弹性悬链线单元，并通过静力和动力拉索问题说明了该单元的实用性。它的准确性和效率被发现可以与文献中提出的一些元素相媲美或更好。初始弯曲或由于变形而呈现弯曲形状的缆索可以使用所提出的单元来建模。电缆的自重可以包括在内，没有任何近似值。也可以包括单元中的预应力。所开发的单元程序可以方便地与现有的牛顿-拉夫森法等非线性程序配合使用。
In this paper a small strain elastic catenary element is presented and its utility is demonstrated through static and dynamic cable problems. Its accuracy and efficiency are found to be comparable or better to some of the elements presented in the literature. Cables that are initially curved or that assume a curved shape as a result of deformation can be modelled using the proposed element. Self-weight of the cables can be included without any approximations. Prestress in the element can also be included. The element program developed can readily be used with the currently available nonlinear codes like Newton-Raphson method.
