摘　　要：钢丝绳芯输送带接头在受拉工况下易发生钢-橡胶界面脱粘失效。脱粘阻力主要来自于钢-橡胶界面粘合力,以及因钢丝绳复杂曲面形状与橡胶紧密贴合而形成的阻力。为研究前者对输送带受拉脱粘行为的影响,文中采用Mooney-Rivlin模型表征橡胶材料特性,采用双线内聚力模型表征界面接触性质,通过试验提取内聚力模型参数并通过有限元仿真验证模型的适用性。基于内聚力模型建立圆柱钢丝绳芯输送带简化模型,对其进行有限元分析,分析其脱粘行为,可为钢丝绳输送带接头的研究提供基础理论支撑。The joint of the steel-cord conveyor belt with tension is prone to the debonding failure of the steel-rubber interface.The debonding resistance mainly comes from the adhesion of the steel-rubber interface and the resistance formed by the tight fitting between the steel-cord complex curved surface shape and the rubber.In this article,in order to explore the influence of the former on the conveyor belt’s tensile debonding behavior,the Mooney-Rivlin model is used to characterize the properties of the rubber materials,and the bilinear cohesive zone model is used to characterize the interface’s contact properties.The cohesion zone model’s parameters are extracted through some experiments,and the finite-element simulation is conducted to verify that this model is applicable.Based on the cohesive zone model,a simplified model of the cylindrical steel-cord conveyor belt is set up,and its debonding behavior is subject to the finite-element analysis.This study provides theoretical basis for research on joints of steel-cord conveyor belts.
