摘要
作为动力学分析的基础,模态分析可以用来确定机械机构自身的振动特性,文章简要阐述了模态分析的基本原理以及在Ansys环境下进行模态分析的步骤,并以一高速旋转圆盘锯片为分析对象,进行带有预应力的模态分析,以此说明在Ansys软件中进行模态分析的方法,并为类似的工程计算问题提供参考。
As the basis of dynamic analysis,modal analysis is performed to determine the vibration features of the me-chanical structure.The paper describes basic principles of the modal analysis and its steps in Ansys.With the high-speed rotating disc saw blade as an analysis object,the modal analysis with pre-stress is performed,to show related methods of modal analysis,which provides reference for similar engineering calculating problems.
