摘要：

为了研究采煤机运行时导向滑靴的实时、动态受力情况，在分析导向滑靴销轴受力特点的基础上，开发了导向滑靴受力检测系统，安装与导向滑靴销轴具有等效强度的销轴传感器，采用无线应变采集模块实现数据的无线传输，实现不同工况下导向滑靴受力的实时在线检测。现场实验表明，斜切进刀时，左、右导向滑靴均承受随机载荷，2个连接耳孔处有效载荷分别为26.1，15.1和45.1，21.5 kN。利用ANSYS软件对测试数据进行处理和分析，得到最大斜切受载时，采煤机左、右导向滑靴连接耳孔处受力最大，分别为173.87，187.85 MPa。测试与分析结果为导向滑靴的设计优化提供重要的理论和数值依据。

Abstract:

To study the mechanical property of guide foot, the detecting system, which was based on non-destructive testing technology (NDT Tech), in which the pin sensors was installed with the same strength as the core shaft of guide foots and whose signal was transmitted online by wireless signal launcher, was designed to detect the force of guide foot under different conditions online by analyzing the force of the pin. Then the field test showed that, under the condition of oblique cutting, the loads of guide foots were at random, and the effective values of ear-plates' loads were 26.1 kN and 15.1 kN in the left guide foot and the right are 45.1 kN and 21.5 kN. By FEA, it's known that the places, where were the maximum stress of the left guide foot and the right one, which were 173.87 MPa and 187.85 MPa, were located at ear-plate of guide foot in the circumstances of maximal force. And testing and analysis results provide substantial theoretical and numerical basis for the design optimization of guide foots.
