| Abstract: | Proceeding from satisfying the construction requirements for wire wrapping of main cables of suspension bridge at different stages, this paper analyzes the influences of the tensile force changes of main cables on the tensioning force of wire wrapping, calculates the minimum tensioning force required by the wire wrapping under the condition of deformation coordination and expounds how the rational tensioning force can be realized in case the home-made ZLC Series Wire Wrapping Machines are used, the formation of the force in the tensioning mechanism and also the methods for adjusting and displaying the force. |
