Abstract

Abstract: In order to reveal dynamic contact and slip mechanisms of steel wires in the main cable of suspension bridge, a self-made dynamic contact and slip test rig of steel wires is employed to carry out dynamic contact and slip tests between parallel steel wires in a single friction cycle. The in-situ observation by high-speed digital microscope system, scanning electron microscope, energy spectrometer and finite element simulation were employed to reveal effects of transverse and longitudinal contact locations, number of cycles, slip amplitude and contact load on dynamic contact and slip characteristics between parallel steel wires (transverse slip, longitudinal deformation, contact state, friction force, coefficient of friction, and stress distribution) and wear mechanisms (wear scar morphology and element distribution). The results show that in a single cycle, dynamic contact states between steel wires are adhesion, gross slip, adhesion and gross slip, respectively. The transverse slip and and friction force of steel wire both exhibit change trends of an increase, the stabilization, a decrease and the the stabilization. Longitudinal deformations of upper and lower steel wires present the overall reverse change trends. Increases of fatigue cycles cause both increases in the transverse slip and longitudinal deformation of lower steel wire. The coefficient of friction shows the change trends of an increase at first, then a decrease, afterwards an increase and the final stabilization with increasing fatigue cycles. Increases of displacement amplitude and contact load cause increases in the average value of transverse deformation at stage 2 of the stroke, and the fluctuation amplitudes of longitudinal deformations of upper and lower steel wires. The coefficient of friction presents an increase and a decrease with increasing displacement amplitude and contact load, respectively. Wear mechanisms consist of adhesive wear, abrasive wear, extrusion wear and fatigue wear in all cases.
