Abstract

The invention discloses amethod and a system for calculating coupling power of a single carrier cable freight cableway. The method comprises the steps of setting calculation parameters based on a freight cableway; Calculating the acting resultant force borne by the bearing cable / traction cable node in the current time step according to the calculation parameters; Based on the calculation parameters and the acting resultant force borne by the nodes bearing the cables / traction cables in the current time step, time steps are increased according to the set time increment step length, the node motion equation is solved, and the acting resultant force borne by the nodes bearing the cables / traction cables in all the time steps is calculated till the preset time period is over. According to the technical scheme provided by the invention, the problems of inaccurate stress calculation and low calculation efficiency of the bearing cable and the traction cable are solved, the tension change results of the bearing cable and the traction cable of the freight cableway in the working process can be accurately and efficiently obtained, and a more accurate calculation basis is provided for design and model selection of the freight cableway.

Description

technical field [0001] The invention relates to a numerical calculation method in the structural design of a single-bearing cable freight cableway, in particular to a single-bearing cable freight cableway coupling dynamic calculation method and system. Background technique [0002] The freight cableway for transmission lines has the advantages of strong applicability and little influence from the weather and external environment. It can effectively solve the problem of mountain transportation of iron tower materials, wires and other materials, and at the same time greatly reduce green compensation and road construction costs. Therefore, engineering construction in complex terrain in mountainous areas been widely applied. [0003] The freight ropeway is a mechanized and semi-mechanized transportation channel with steel wire rope as the main body and transmission through the wire rope. This kind of mechanized transportation channel mainly relies on various working structures r...
