Abstract
The contact parameters of materials have great influence on the results in structural dynamic analysis, but the friction relation between wires has not been solved, which often causes the simulation error. To improve the accuracy of the finite element simulation, this paper study the friction and load relationship between wires of galvanized steel strand, testing material friction coefficient and drawing load of single wire for different length, obtains the force-displacement curve of core wires. The results show the friction coefficient between wires of galvanized steel strand is from 0.42 to 0.52, the friction force and the length of the wires present a linear proportional relationship; The maximum static friction of core strands is independent of drawing velocity.
