摘要
模态分析用于确定结构的振动特性,它是谐响应分析、瞬态动力学分析及谱分析等其他动力学分析的起点。运用ANSYS软件对某悬臂钢板进行模态分析,得到悬臂钢板的前5阶固有频率和振型,并与试验得到的结果对比,确定悬臂钢板的振动特性,从而为以后研究各种实际结构振动提供了依据。
Modal analysis,as a starting point of harmonic response analysis,transient analysis,spectrum analysis and other dynamics analysis,is used to determine the structural vibration performance. It was performed modal analysis of a cantilever plate by the software of ANSYS,and the virtual result of first five natural frequency and mode of vibration were got. Which were compared with experimental result to determine vibration performance of cantilever plate.Which would provide a basis for study on actual structure in the future.
