摘　　要：为了研究镐齿形状对其强度的影响,取几何尺寸相同、结构形状不同的三种截齿进行比较分析,建立了三种不同形状镐形截齿的结构模型,利用ANSYS软件在同样载荷作用下对各个截齿进行应力分析,得出各截齿的变形图和应力分布图,掌握了每种截齿工作时各点应力大小和易受损的位置,所得结果为正确选择和合理设计截齿结构以及改进截齿的设计、改善镐形截齿的受力状况、提高截齿工作的可靠性和使用寿命提供了重要的依据。In order to study the impact of point-attack pick shapes on picks’ strength,three picks with the same geometry and different structural shapes were selected for a comparative analysis.Based on the study,the structural models for three different point-attack picks were established.Subsequently,each pick stress was modeled under the same load using ANSYS to obtain its deformation map and stress distribution.Also,the magnitude of stress at various points and the vulnerable locations on each pick were identified under a normal working condition.The results provide an important basis on the selection and rational design of picks.
