【摘要】 本文介绍一种利用铣床建立的滚筒采煤机截割阻力摸拟试验装置。根据所选定的试验参数,利用相似性法则,确定了各参数的相似系数,建立了1:4的摸拟试验台,并研制了测扭、测三向力的传感器。更多还原

【Abstract】 With a miller as a makeshift, a 1/4 simulation stand is set up for testing cutting resistances of the drum shearer. In accordance with similarity rules, test factors arc selected and assigned similarity coefficients. In addition, sensors are developed for measuring torques and stresses on the three axes更多还原
