为了研究液压拉杠在恶劣工况下的力学性能，首先对滚筒采煤机整机进行载荷分析，计算在斜切状态下滚筒和滑靴处的载荷情况，然后利用计算结果对液压拉杠进行力学分析，研究在不同煤层倾角和俯仰角下各液压拉杠的拉力变化情况。利用Workbench分析了受载严重液压拉杠的有限元应力分布，并基于疲劳累积损伤理论，对液压拉杠进行了疲劳寿命预测。研究结果准确地反映了液压拉杠在实际工作时的力学性能，为采煤机的设计计算及实际生产研发提供了理论依据，也对同类元件的进一步研究有一定的参考价值。

To study the mechanical properties of hydraulic rods under bad conditions ,the loads of whole drum shearer were analyzed and the loads of drum and sliding shoes were calculated under the condition of oblique cutting .The variation of each hydraulic rods tensile force with different coal seam dip angles and pitching angles was researched .The stress distribution of hydraulic rod with most serious bearing load was analyzed by using Workbench .Based on the fatigue cumula‐tive damage theory ,the fatigue life of hydraulic rod was predicted .The research results reflected the mechanical properties of hydraulic rods in the practical work accurately .It provides theoreti‐cal basis for design ,calculation and practical production development of shearer ,and also has ref‐erence value for further research of the same type components .
