Abstract

The invention discloses a multi-carrier-cable freight cableway coupling power calculation method. The method comprises: setting calculation parameters based on a freight cableway; Based on the calculation parameters, the acting resultant force borne by the nodes of the bearing cable / traction cable and the rotating resultant moment borne by the load in the current time step, increasing the time step according to the set time increment step length, solving the node motion equation and the load rotation equation, and calculating the acting resultant force of the bearing cable / traction cable nodeand the rotation resultant moment of the load until the preset time period is ended. According to the technical scheme provided by the invention, the stress change of the freight cableway bearing cable and the traction cable in the working process and the deflection angle of the load can be accurately and efficiently obtained, and a more accurate calculation basis is provided for the design and model selection of the freight cableway.

Description

technical field [0001] The invention relates to a numerical calculation method in structural design of a multi-bearing cable freight cableway, in particular to a coupling dynamic calculation method and system for a multi-bearing cable freight cableway. 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...
