Problems solved by technology
[0003] The existing rope design method only considers one parameter, and does not integrate the various properties of the steel wire rope, so the designed rope is difficult to meet the requirements of different working conditions; the existing rope design method does not give a linear expression of the stiffness coefficient. It is very difficult to solve, and it is difficult to calculate the twisting parameters of the strands and the steel wires in the strands

The invention discloses a rope design method with multiple parameters synthesized and belongs to the technical field of steel wire rope product design. According to the method, on the basis of the axial rigidity coefficient, the torsional rigidity coefficient, the axial torsional coupling rigidity coefficient and the flexural rigidity coefficient of a spirally-twisted body, the rotational resistance, the tensile property and the flexibility of a rope are designed synthetically. All the rigidity coefficients are functions of diameters of steel wires in the rope and twisting parameters of the rope, design and calculation of twisting parameters of strands in the rope and wires in the strands can be realized according to requirements for properties of the steel wire rope, design of the rope under different working conditions can be realized, by the aid of linear expressions of the rigidity coefficients of the rope, the calculation is convenient, the consumed time is little, and the twisting parameters of the rope can be calculated very easily.
Description
technical field [0001] The invention relates to a steel wire rope design method, in particular to a comprehensive multi-parameter rope design method suitable for steel wire rope design under complex working conditions. Background technique [0002] Steel wire rope is an important component in mine hoisting, elevator lifting and other fields, and the performance of the rope is directly related to the safety and reliability of the hoisting system. As the hoisting load increases and the working conditions become more and more complex, higher requirements are put forward for the various properties of the wire rope. [0003] The existing rope design method only considers one parameter, and does not integrate the various properties of the steel wire rope, so the designed rope is difficult to meet the requirements of different working conditions; the existing rope design method does not give a linear expression of the stiffness coefficient. It is difficult to solve, and it is diff...
