| 摘 要： | 采煤机截齿截割煤体时,截齿承受随时间而变化的动载荷。为了掌握采煤机截齿工作时应力、位移的分布情况,避免共振现象的发生,对它进行模态分析和动态设计具有重要意义。所述模态分析和动态设计的内容和步骤,可为采煤机截齿的设计提供理论依据。

| Abstract: | The cutter of the coal mining machine bears dynamic load varying with time during excavating coal. To grasp the stress and displacement distribution of the cutter, to avoid the happening of sympathetic vibration, carrying out modality analysis and dynamic design to the cutter are very important. The content and process of modality analysis and dynamic design mentioned in the thesis may provide a theoretic basis for the design of the cutter. |
