摘　　要：为了研究钢丝绳直径、结构和环境温度对钢丝绳疲劳寿命的影响,选择用于太空安全绳的钢丝绳,通过Ansys Workbench分析软件建立钢丝绳多场耦合有限元模型,计算不同因素对钢丝绳应力的影响。根据应力疲劳理论,导入不锈钢材料的应力-寿命曲线,对钢丝绳的疲劳寿命进行仿真分析,通过钢丝绳的疲劳寿命云图可以发现,钢丝绳的直径和结构对钢丝绳的疲劳寿命影响较大,环境温度对钢丝绳的疲劳寿命影响较小。根据仿真结果和具体使用条件,遴选出最适合用于太空安全绳的钢丝绳。To study the effect of the steel rope diameter,structure,and ambient temperature on the fatigue life of the steel rope,the steel rope for space safety rope is selected. The multi-field coupling finite element model is developed for steel rope in Ansys Workbench to calculate the effect of different factors on the stress of steel rope. According to the stress fatigue theory,the stress-life curve for stainless steel material is imported,in order to perform simulation analysis for fatigue life of the steel rope. It＇s found through the fatigue life cloud picture that diameter and structure of the steel rope has great effect on the fatigue life,while ambient temperature has little effect. According to the simulation result and specific service condition,the steel rope best fit for the space safety rope is selected.
