catenary

基本解释

Much of the book is about their practical problems—thrust lines, the catenary curve and groin vaulting.
该书大部分都是关于他们实际存在一些的问题—外扩的线条，垂曲弧，穹型拱顶。
In nature, cosh(z) is the equation for the shape of a hanging rope connected at two ends, known as a catenary.
实际上，cosh(z) 的结果相当于一根吊绳两端相连后得到的形状，即悬链线。
To determine the catenary curves of arches, he would tack a sketch of a foundation plan on the ceiling, hang loops of string, and attach weights along the loops in proportion to down forces.
为了确定拱顶的链状曲线，他会用大头针将基座草稿钉到天花板上，吊上几圈绳子，在绳子上加重，与向下的力相符。

the curve assumed by a heavy uniform flexible cord hanging freely from two points. When symmetrical about the y-axis and intersecting it at y = a, the equation is y = a cosh x/a
of, resembling, relating to, or constructed using a catenary or suspended chain

The convergence and numerical stability are satisfactory. Through analyzing the different examples,the conclusion that the catenary elements can work precisely for static or dynamic cables with arbitrary sag is drawn.
不同的算例表明 ,悬链线单元模型无论对小垂度还是大垂度索结构的静力和动力分析都具有很高精度 ,而且计算工作量大大减少。
