采煤机导向滑靴力学在线测试与分析
Research on online testing and analysis of guide foot force of shearer
摘要
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 M Pa and 187 .85 M Pa ,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 .关键词
