根据采煤机采煤工艺,在分析采煤机工作姿态变化规律的基础上,推导双刀示范记忆截割数学模型和再现轨迹时采煤机姿态与示范截割时的姿态关系,并分析误差,最终论证利用推导出的算法对滚筒调节并使之到达示范截割模式下的轨迹的可行性。 According to the mining technology of shearer, based on the analysis of the change law of shearer working attitude, the relation between the attitude of shearer and the gesture of model cutting when deducing the mathematical model and trajectory of the dual-knife model memory cutting was analyzed. The error Finally, the feasibility of using the deduced algorithm to adjust the drum to reach the trajectory in the demonstration cutting mode is demonstrated.
