应用弹性曲梁理论,对钩号08的起重吊钩进行了理论分析,在载荷作用下,计算出危险截面上的最大工作应力。然后用有限元分析软件ANSYS对该吊钩进行了数值仿真计算,得到吊钩在载荷作用下的应力分布图。最后对计算出的理论解和数值解进行对比,得出结论,为吊钩的结构设计和进一步的优化设计提供必要的理论依据。 Based on the theory of elastic curved beam, the lifting hook of hook No. 08 is theoretically analyzed. Under the action of load, the maximum working stress in dangerous cross section is calculated. Then the finite element analysis software ANSYS was used to carry out the numerical simulation of the hook to obtain the hook stress distribution under load. Finally, the calculated theoretical solution and numerical solution are contrasted, and the conclusion is reached that provides the necessary theoretical basis for the structural design and further optimization design of the hook.
