摘要
介绍了模态分析的基本原理,并以架空索道塔架为例,运用ANSYS软件对其进行结构模态有限元分析,计算得出该塔架的前10阶模态频率及相应的主振型,为其设计和使用提供了必要的依据。
The theory of modal analysis is introduced. Through the modal analysis on the truss tower of aerial ropeway,the inherent frequencies and mode shapes of the first 10 modes are obtained respectively by ANSYS software. It provides the theory for the design and application of truss tower.
