摘要
在架空索道的设计中,悬链线理论是人们公认的最接近真实情况的设计理论,但是由于悬链线函数属超越函数,计算上的困难使其在工程应用中极为不便。从索道悬链线的标准线形出发,给出了无荷状态下悬索的数学模型,并讨论了在已知不同条件下的迭代求解算法,为架空索道的设计计算提供依据。
Catenary algorithm is regarded as a theory which is much close to the truth in cableway design. But it′s very inconvenient for the application of engineering because it belongs to surpass function. Based on the standard curve of the catenary, this paper gave the systematic discussion about the answering formula and iterative algorithm for tension coefficient of unloading flexible cable under different known conditions of state variable.
