論文摘要:

研究球型鑲齒滾刀破巖過程中刀盤轉速、鉆壓、鑲齒數(shù)、刀盤間距以及貫入度5 種因素對破巖比能的影響,利用ABAQUS 有限元計算軟件,建立雙排滾刀直線切割圍巖的動力顯式模型;基于正交試驗法,設置五因素四水平正交試驗L16(45),通過極差分析和方差分析找出不同因素變化對破巖比能的影響規(guī)律,并對比分析最優(yōu)組合和最不利工況下滾刀滾動力和破巖效果。研究結果表明:影響滾刀破巖比能因素的主次順序依次是鉆壓、刀盤排距、轉速、刀齒數(shù)和貫入度;適用于中風化凝灰?guī)r互層的鉆具參數(shù)為轉速12.56 m/s,鉆壓25 kN,刀齒數(shù)34 個,刀盤排距35 mm,貫入度1 mm,此時的破巖比能為0.382 8 MJ/m3,優(yōu)化效果較好。
