摘要： 通過(guò)對(duì)沖擊和研磨力學(xué)模型、振動(dòng)磨機(jī)兩自由度線性振動(dòng)模型、非線性碰撞振動(dòng)模型、離散磨介群動(dòng)力學(xué)模型的比較分析,離散磨介群動(dòng)力學(xué)模型可以更準(zhǔn)確地定量分析整個(gè)磨筒流場(chǎng)內(nèi)磨介各物理量的變化規(guī)律以及磨介群內(nèi)部\\\"粒子\\\"之間耦合關(guān)系.在此基礎(chǔ)上,根據(jù)離散磨介群動(dòng)力學(xué)模型所描述的磨介群運(yùn)動(dòng)學(xué)特征,借助于電子計(jì)算機(jī)模擬了不同參數(shù)條件下離散磨介群的運(yùn)動(dòng)軌跡,結(jié)果說(shuō)明對(duì)應(yīng)于振動(dòng)磨機(jī)不同工作參數(shù)的組合,磨介群有著不同的工作狀態(tài)和作用方式,能量分布亦有不同.這也為振動(dòng)磨機(jī)的進(jìn)一步研究和開(kāi)發(fā)提供了理論依據(jù).圖3,參7. The comparative study of 2-DOF Linear vibration model,nonlinear collision model of the vibration mill and the disperse milling medium group model showed that the disperse milling dynamical model could be more accurate quantitative analysis the medium group physical changes of the entire tube mill flow,and described relationship between the \\\"particles\\\" inside the medium group. Based on this and According to disperse milling medium group kinematics characteristic which the disperse milling medium group model ...
