Numerical Calculation and Analysis of Mechanical Strength of Steel Wire Product

Abstract

To obtain the influence law of laying combination and lay pitch multiple on mechanical strength of steel wire product, we took 6×19IWS right lang lay and right regular lay wire ropes as examples, combining with the strength theory, nonlinear finite element analysis were carried out with ANSYS software. The simulation results show the mechanical strength of the lang lay wire rope is better than that of the regular lay at the same lay pitch multiple; the lay pitch multiple of rope has a great impact on mechanical strength of steel wire product, however, the impact trend is similar among difference laying combinations, meanwhile the effect of the lay pitch multiple of strand is relatively small. Finally, finite element model for wire rope was verified reasonable through tensile experiment. Research results have important applications value for structural design and rational use of wire rope.
