采煤机牵引部液压系统的压力反馈研究

Study on the Pressure Feedback in the Hydraulic System of Drum Shearer

本文通过理论分析和计算机仿真,论述了采煤机牵引部液压系统进行压力反馈的必要性,建立了压力反馈环节的合适数学模型,所得结论可作为今后设计新型采煤机液压系统的一般原则,也可供现有采煤机牵引部液压系统的改进设计参考。

In this paper, by means of the theoretical analysis and computer simulation, the neces-sity of pressure feedback in the hydraulic system of the haulage unit of drum shearer has been described, and the mathematical model of the feedback link has been established. The results obtained are useful to the design of new hydraulic system of shearer or the im-provement on the existing hydraulic system of drum shearers.
