Abstract
Investigated the spatial deformation of the steel rope with the account of friction between the turns. Steel ropes in the aggregate as are a flexible design with a complex geometrical structure, therefore, used a mathematical model based on the numerical solution of system of nonlinear differential equations describing the elastic deformation of the flexible spatially curved rods. The solution of equations based on joint application a method of continuation on a parameter, and the method of Newton-Kantorovich. Application of the method described allows to investigate the spatial deformation of the steel rope with consideration of friction, as a functionally specified loading with an arbitrary vector of magnitude and direction for every coil of wire rope. In this case the output parameters of the task can be numeric and graphic values of all internal forces and bending moments as in a state of aggregation of the rope, and in its separate branches. Presented numerical results showing the capabilities of the method.
