Abstract

The load of wire in helicopter live-line work is analysed, and the calculation method for cable lifting of helicopter is proposed based on catenary theory of suspension cable. The nonlinear equation set is established to calculate the lifting force of the helicopter. The tangent stiffness matrix of the iteration method is expressed in explicit formulation and a numerical study is performed for two cases in practical engineering of helicopter live-line overhaul. The results show the method is a high speed, convenient and accurate numerical method which can be used in analysis of suspension bridges, cargo ropeways and other various types of cable structures for the designer's reference.
