为了探究滚筒采煤机导向滑靴和支撑滑靴的受力规律，综合考虑采煤机的结构参数、运行参数及煤层倾角对整机力学特性的影响，建立采煤机整机力学模型及状态方程。在单截齿随机载荷的基础上，应用滚筒载荷的叠加算法，得出采煤机在随机载荷作用下前导向滑靴比后导向滑靴的受力波动较大，同时给出各力的大小和方向。
為瞭探究滾筒採煤機導嚮滑靴和支撐滑靴的受力規律，綜閤攷慮採煤機的結構參數、運行參數及煤層傾角對整機力學特性的影響，建立採煤機整機力學模型及狀態方程。在單截齒隨機載荷的基礎上，應用滾筒載荷的疊加算法，得齣採煤機在隨機載荷作用下前導嚮滑靴比後導嚮滑靴的受力波動較大，同時給齣各力的大小和方嚮。

In order to explore the law of load on the guide and support slippers, the mechanical model and state equations of whole shearer are established under comprehensive considering the influence of structural and operational parameters and the inclination of coal seam on the mechanical properties of shearer. Based on the random load of single bit, the additive operation of drum load is applied and comes to the conclusion that the fluctuation of load on the fore slippers is more than that on the rear ones under random load. The amount and orientation of loads are Riven.
