| 摘 要： | 利用有限元分析软件ANSYS9.0的模态分析功能，计算了TR1000型凿岩机伸缩臂部分的固有频率和振型，并将有限元计算结果与试验模态分析结果进行了对比。结果表明试验模态分析与有限元分析基本一致，可为伸缩臂的设计提供参考。同时指明有限元模态分析比试验模态分析具有方便、快捷、成本低、可重复性强等优点，尤其适合求解大型复杂结构系统。 |

| Abstract: | In the paper, the inherent frequencies and vibration modes of the telescopic booms of TR1000 rock drilling jumbos are calculated by means of the modal analysis function of the finite element analysis program of ANSYS9.0 and comparison is made between the FEM calculation results and the modal testing analysis results. The comparison indicates that the modal testing analysis helpful rapid, for the designing of the results are in good agreement with the FEM calculation results. The analytical results are telescopic booms. The study indicates that the FEM modal analysis is more convenient, cost-saving and repeatable than the modal testing analysis and is especially powerful for large and complicated structures. |
