This paper considers the towline as "flexible suspended cable with rigidization" model, and applies catenary theory to analyzing the stress of the towline and to performing the simulation calculation.

To replace the catenary algorithm, those three methods just satisfied the needs of .

Based on the catenary theory of cables,an iteration method was presented for the shape-finding analysis of spatial-cable suspension bridges.

Based on the catenary theory,with Newton iteration numerical method,mathematics models of design of suspension rope of strop ropeway are established,facilitating installation of strop ropeway,improving safe performance,providing the scientific theory proof of suspension rope design of suspension rope.

The stiffened catenary theory is applied to establish the static equilibrium governing differential equation of a pipe element,and the solution equations of total configuration of the pipeline from a lay-barge over a stinger to the sea floor are completely derived.

<abstract>e system consisting of JL/G1A-125-26/7 steel-cored aluminium stranded wire and suspension clamp is taken as an example to investigate the fretting damage characteristics of overhead electrical conductors.

He considers that the unit length self-weight load of the overhead line is distributed uniformly along the line suspension curve,change at the point acted by the curve load is not continuous(with s.
