| 摘 要： | 塔式提升机引起的机器剧烈振动会导致机件的损坏。因此，以焦作工学院提升机实验室的井塔为对象作了模态分析。利用MSC.PATRAN／NASTRAN有限元分析软件，详细列出了单元划分、节点约束、材料特性，得出了井塔振动的前十阶自然频率及模态。根据实验结果及频率对模型物理参数频率的灵敏度来修正有限元模型，求出最后的有限元结果。

| Abstract: | The vehement vibration caused by a shaft-tower hoist can lead to damages to machines. The paper introduces the mode analysis, based on the experimental shaft-tower of hoist laboratory in jit. The layout of calculational elements, restraint of nodes and material performance are listed in details. The finite element model is updated by experiment and sensitivity of frequency to physical parameter. |
