By modifying the loading ratio and scale factor, get groups of fatigue life values of wire rope. Finally, record and arrange the fatigue life value of wire rope under bination of loading ratio and scale factor in a table, and find out that the fatigue life of wire rope decreases when the load amplitude increasing. Key words: wire rope; alternating load; fatigue life; virtual fatigue test 引言劳设计 0 。 钢丝绳以其独特的螺旋捻制结构和良好的弹采用名义应力法对钢丝绳进行疲劳分析其虚 , 塑性被广泛应用于各领域也正是由于其自身复杂拟疲劳试验技术路线如图所示 。
