摘要

以某汽车助力泵夹缝旋压皮带轮为研究对象，探讨不同循环特性下的应力极限图；针对旋压皮带轮工作过程中承受的应力复杂性，借助ANSYS软件，采用了安全因子法和应力极限图法对其进行了寿命评估。结果表明：该汽车助力泵夹缝旋压皮带轮工作在不同的循环特性下，处于复杂的交变应力状态，其在该状态下运行是安全的。该疲劳评估方法为缺乏S-N数据的旋压皮带轮疲劳寿命设计提供了可靠依据。

Abstract

Taking spinning pulley with a slit in the automobile booster pump as study object, the stress limit diagram with different cycle characteristics are discussed. The fatigue life of spinning pulley under the complexity of the stress are assessed by using the stress limit diagrams and safety factor method by ANSYS. The results show that, the spinning pulley with a slit in the automobile booster pump are in different cycle characteristics and complex state of alternating stress, but it works safely. The reliable basis is provided for designing fatigue life of the actual spinning pulley without S-N data.
