采煤机螺旋滚筒的性能好坏对整个采煤机的受力状况、传动装置中负荷的脉动程度、采煤机工作的稳定性等有着重大影响。早期的研究主要是通过实验对截齿和滚筒上的负荷进行研究。随着计算机模拟技术的出现,为螺旋滚筒负荷的研究开辟了一条广阔的道路。使得定量研究采煤机负荷成为可能。本文介绍对螺旋滚筒上的平均负荷进行的模拟研究。一、截齿和滚筒平均负荷的数学模型在一般情况下,应以磨钝截齿上的负荷进行研究。这时,沿三个互相垂直方向的分力可按下式确定。
Shearer spiral drum performance is good or bad for the entire Shearer stress conditions, the pulsation of the load in the transmission device, Shearer has a significant impact on the stability of the work. Earlier research mainly studied the load on picks and rollers through experiments. With the advent of computer simulation technology, the spiral roller load research has opened up a broad road. Making it possible to study the shearer load quantitatively. This article presents a simulation study of the average load on a spiral drum. First, the average load of the cutter and the drum mathematical model Under normal circumstances, the load should be ground with a blunt pick on the study. At this time, along three mutually perpendicular component of force can be determined by the following formula.
