Strukturmechanische Berechnung der Kinematik im Drahtseil
The kinematics of a wire-rope have been investigated and are described in what follows. In the first place, a kinematic description of the wires and strands in a wire-rope is given. Other equations are developed to describe the movements and the tensions in these wires and strands. These equations were computer processed to determine the internal characteristic values associated with these movements and imposed strains. The prototype programme was used to calculate the results for a standard construction and these were compared with existing information, when close agreement was obtained. The same approach was taken for a fully-closed wire-rope when certain differences were noted with respect to unraveling. To eliminate these differences, a detailed investigation was made using the finite-element method and on the basis of the information obtained, correction functions were introduced into the programme. The resulting calculations then provided a close match between the values obtained by the two methods. Finally as an extreme case, the consequences of running a wire over a friction winch were calculated and compared with practical observations - this provided an explanation of phenomena which previously could not be understood.
