有限单元法是近年来发展起来并广泛应用于力学工程领域的一种计算方法。采用计算机有限单元分析法软件ＳＵＰＥＲＳＡＰ９１对一种应用于高温环境中的铸造吊钩进行了应力分析，并对可能出现的破坏情况提出了设计改进措施。
Finite element method is developed in recent years and widely used in mechanical engineering field of a calculation method. The finite element analysis software SUPERSAP91 is used to analyze the stress of a cast hook used in high temperature environment and the design improvement measures are put forward for the possible damage.
