客运索道线路跨距对张紧行程的影响

Influence of the span of passenger ropeway line on tensioning stroke

介绍客运索道的几种张紧方式,通过抛物线悬索理论得出张紧行程的计算方法,得到客运索道线路中大跨度、集中载荷的工况与张紧行程的关系,结合实例证明张紧行程理论计算方法具有参考意义。分析案例结果,得到张紧行程对钢丝绳编结具有重要参考意义,可指导工程实际应用。

In the paper, several tensioning types of passenger ropeway are introduced, and the calculation method of tensioning stroke is obtained based on the theory of parabolic suspension cable. The relationship between the condition of large span and concentrated load and tensioning stroke in passenger cableway line is also found. Moreover, the examples show that the theoretic calculation method of tensioning stroke has certain reference meanings. According to the analysis results, the method is of important reference significance to wire rope braiding and of guiding significance to engineering practice.
