采煤机牵引部传动系统扭振分析

Analysis of Torsional Vibration of Shearer Hauled-part Drive System

利用传递矩阵法建立了采煤机牵引部传动系统的扭转振动模型,通过计算其固有频率及在低阶模态中的势能分布率及模态柔度,找出该采煤机牵引部传动系统的薄弱环节,为改善其动态特性提供了理论依据。

We have built the torsional vibration model of haul part driver system in shearer by the transfer matrix method. The weak segment has been find out through computing the natural frequency, distributive law of potential energy and modal flexibility at low order modal. Thus, we provide the theory evidence for improving the dynamic characteristics.
