摘要
探讨了截割硬岩时截割线速度对截齿受力和应力分布的作用情况,通过Pro/E三维建模,利用ANSYS对不同截割线速度下截齿受力情况进行有限元分析。分析结果表明,随着截割线速度的增加,截齿所受最大应力减小,而随着线速度的继续增加,最大应力值减小的幅度降低。
The effect of the cutting pick stress with different cutting linear velocity was analyzed by using Pro/E and ANSYS finite element method. The result showed： as the cutting linear velocity raised, the cutting pick stress brought down. When the cutting linear velocity raised further, the reduce amplitude of the maximum stress slowed down.
