摘　　要：为了探究疲劳加载对橡胶钢丝复合体粘合性能的影响,采用动态测量与静态测量相结合的办法,研究疲劳频率、疲劳加载次数和动态疲劳后停放时间对橡胶钢丝复合体粘合性能的影响,结果表明,随着疲劳频率的逐渐提高,试样断裂时拉伸伸长量表现出明显降低的趋势;橡胶钢丝复合体试样抽出粘合力和钢丝帘线的表面附胶量均随着疲劳次数的增加先增大后减小;同样,粘合力随着停放时间的延长也是先增大后减小,并且橡胶钢丝复合体疲劳后粘合力的恢复主要发生在停放初期。In order to explore the influence of fatigue loading on the adhesive properties of rubber-steel wire com-plexes.In this paper,dynamic and static measurement methods are integrated using to research the influence of these items on the adhesive properties of rubber-steel wire complexes,which items contain fatigue frequency,fa-tigue loading times and storage time after dynamic fatigue measurement.The results show that the tensile elon-gation of sample at fracture shows obviously decreased with the increasing of fatigue frequency.The extraction force of rubber-steel wire complexes sample shows a variation tendency of firstly increases and then decreases with the increase of fatigue imposed times.In addition,the steel cord surface adhesive amount shows a variation tendency of firstly increases and then decreases with the increase of fatigue imposed times.The adhesion force also has a variation tendency of firstly increases and then decreases with the increasing of storage time,and the recovery of adhesion force after fatigue imposed mainly occurred in the initial stage of storage time.
