基于曲梁理论的起重机非标准吊钩分析

Analysis of Crane Non Standard Hook Based on Curved Beam Theory

采用曲梁理论计算了直柄双钩危险断面的应力值,将理论计算得到的应力值和有限元法得到的结果进行比较,验证了曲梁理论计算方法的有效性。作为参考比较,同时计算了直梁线性理论方法计算所得同样断面的应力值。

In this paper,the stress value of dangerous section of double hook with straight handle is calculated by using curved beam theory,and the stress value obtained by theoretical calculation is compared with that obtained by finite element method,which verifies the effectiveness of the calculation method of curved beam theory.As a reference,the stress values of the same section calculated by the linear theory of straight beam are calculated.
