摘要针对螺旋卸船机施工中异常物料运动影响机械使用寿命的问题,构建了螺旋卸船机施工转料过程的运动模型,使用MATLAB软件仿真分析不同卸料口倾斜角度与螺旋转速对物料运动轨迹的影响,确定了2种参数的优化设置策略。结果显示,螺旋卸船机在位置2时施工的物料卸料轨迹包络的y轴长度在14 m左右,明显小于螺旋卸船机在位置1时的对应数值。当卸料口倾斜角度参数为90°时,施工阶段物料对转料头带来的冲击磨损最小。当螺旋卸船机螺旋转速较高时,选择曲率半径更大的转料头能减少螺旋卸船机整体结构受到的卸料冲击,并减少施工对机械本身带来的不可逆损害。该结果有利于改进螺旋卸船机的施工日常运转模式。 In response to the issue of abnormal material movememt affecting the mechanical service life during the construction of a spiral ship unloader,this study constructed a motion model for the material transfer process of the spiral ship unloader,and used MATLAB software to simulate and analyze the effects of different unloading port tilt angles and spiral speeds on the material movement trajectory,two optimization setting strategies for parameters have been determined.The results show that the y-axis length of the material unloading trajectory envelope of the spiral ship unloader at position 2 is about 14 m,which is significantly smaller than the corresponding value of the spiral ship unloader at position 1.When the inclination angle parameter of the discharge port is 90°,the impact wear caused by the material on the transfer head during the construction phase is the smallest.When the spiral speed of the spiral ship unloader is high,choosing a turning head with a larger curvature radius can reduce the unloading impact on the overall structure of the spiral ship unloader and reduce irreversible damage to the machinery itself caused by construction.The result is beneficial to improve the daily operation mode of spiral ship unloader.
