采用大型通用有限元软件ANSYS／LS-DYNA，对受冲击的直柄吊钩进行动力学分析，得出其应力和位移分布图，从理论上对吊钩受冲击时的危险区域进行了分析研究。为吊钩进一步的结构设计及安全评价提供了必要的理论依据。 This paper calculates and analyzes the lifting-hook by using large-scale finite element software ANSYS, and gets the distribution of the stress and displacements when it is impacted. The paper also investigates the usual dangerous section of the lifting-hook in theory, and provides essential theoretic gist for further improving its structure and security evaluation.
