In order to determine the normal,tangential,critical stress and other parameters of the bilinear wire rope cohesion model,a parameters construction and verification method was proposed based on the wire rope cohesion model.Firstly,the theoretical model of cohesion was established to analyze the relationship between the tensile bond strength and the displacement in the direction and the tangential direction.Then the normal and tangential tensile bonding strength test samples were prepared by a small vulcanization device,and the parameters were measured by a universal tensile testing machine.Finally,based on the bilinear cohesive model parameter values extracted from the experimental results,the finite element simulation software ABAQUS was used to simulate and verify the experimental process.The experimental results show that the maximum error between the simulation results and the experimental results is about 2.7%.Accurate determination of the required cohesion parameters of the wire rope-rubber bonding interface is suitable for describing the adhesion and failure of the steel-rubber interface.
