| 摘 要： | 用ANSYS软件对悬臂梁进行有限元模态分析，得到悬臂梁的固有频率和振型。求解悬臂梁横振动方程，得到悬臂梁横振动的固有频率及横振动的一般解。利用MATLAB软件画出其振型曲线，与ANSYS分析结果吻合极好，验证了用ANSYS软件进行模态分析的可靠性。

| Abstract: | In modal analysis based on ANSYS, we can get natural frequency and modal shapes of a cantilever beam. By analysis of vibration equation of cantilevered beam, the natural frequency can also be got and modal shapes can plot by MATLAB software. They match well with the previous results. It shows the reliability of using ANSYS for modal analysis. |
