摘　　要：针对传统吊钩分析单一等问题,建立起重机吊钩的模型,然后导入Ansys分析软件中展开有限元分析,得到了吊钩的应力应变分布特点,并基于极限承载法对新标准所采用的吊钩材料进行分析。结果显示:吊钩最大应力达到228.434MPa,小于材料许用应力,最大变形约为0.503mm,相对较小;更换材料后,吊钩的极限承载能力增加,可相应提升起重量,以获得较好的材料利用。Considering problems on traditional hook,such simplified analysis,this paper establishes a model of crane hook,and introduces the model into Ansys analysis software for finite element analysis,obtains the stress and strain distribution characteristics of hook,and analyzes the hook materials used in the new standard by using the limit bearing method.Results show that the maximum stress of the hook is 228.434 MPa,less than the allowable stress of the material,and the maximum deformation is about 0.503 mm,a relatively small value.Since the ultimate bearing capacity of the hook increases after the material is replaced,the lifting weight can be correspondingly increased to better utilize the material.
