摘要
本文通过动态直剪仪这一新的技术手段,对松散矿石的动态特性进行了研究,探讨了振动场中散体剪切的应力-应变全过程,揭示了振幅、振频、水份及不同激振方式等因素对散体动特性的影响程度。
By the use of the new technical equipment--vibratory direct shear tester, the whole stress-straincurves of broken ore during shear process have been investigated. And the influences of amplitude, fre-quency, moisture content, different exciting styles and other factors on the dynamic characteristics ofbroken ore have been also discussed in this paper.
