摘要
应用AN SYS通用有限元程序对指数型变幅杆进行了模态分析,得到了纵振动共振频率,位移节点,放大系数等参数。与理论分析结果比较,表明有限元法获得了较高精度。
Normal modes of a exponential pole are analyzed utilizing finite element method. Some important characteristic parameters such as resonance frequency vibration mode and magnifying factor are obtained. The comparison with the results in theory shows the modal analysis has obtained accurate results.
