摘　　要：扒装机构是钻装机的重要组成部分,扒装机构在工作过程中当铲斗斗齿接触地面硬石时会受到岩石的冲击载荷。为了确定冲击载荷对扒装机构典型工况下的影响,针对CMZY2-400/35型钻装机进行研究,通过三维软件SolidWorks对扒装机构进行模型建立和运动学仿真分析,得出典型工况下铲斗斗齿尖线性速度并计算出冲击载荷。利用AnsysWorkbench软件对扒装机构典型工况模型进行瞬态动力学分析,得到其最大等效应力和最大变形云图,分析结果表明,扒装机构在冲击载荷下满足强度要求,最大应力发生在斗齿齿根和主刀板焊接位置。The grilled mechanism is an important part of the drilling loader.When the bucket tooth contacts the hard rock on the ground,the grilled mechanism can be impacted by the rock.In order to determine the effect of impact load on the grilled mechanism under typical working conditions,the CMZY2-400/35 drill loader is studied.The model of the grilled mechanism is established and the kinematic simulation analysis is carried out through the SolidWorks.The linear speed of the bucket tooth tip under typical working conditions is obtained and the impact load is calculated.The transient dynamic analysis of the typical working condition model of the grilled mechanism is carried out by using the AnsysWorkbench,and the maximum equivalent stress and maximum deformation cloud diagram are obtained.The analysis results show that the grilled mechanism meets the strength requirements under the impact load,and the maximum stress occurs at the welding position of the tooth root of the bucket tooth and the main cutter plate.
