摘　　要：基于有限元分析理论,利用ANSYS10.0有限元分析软件中的Block Lanczos模块对自行设计的搅拌摩擦焊用测力八角环进行了模态分析。提取了前12阶振动频率和相应振型,分析了各阶振型的特点。总结了测力八角环在结构设计以及运行时应注意的问题,也为后续的动力学分析提供了理论依据。Based on the finite element analysis theory,Lanczos module of the ANSYS10.0 finite element analysis software is used to make model analysis of the octagon ring-type dynamometer,which is designed for the friction stir welding.Firstly,this paper gets its model analytical calculation of the finite element,extracts its first 12 orders＇ vibration frequencies,and obtains their corresponding vibration models.It also analyzes each order mode,and summarizes the characteristics of the octagon ring-type dynamometer of its structural optimization design and some problems in the operation,which should be paid attention to,and also provides some theory basis for its further dynamics analysis.
