摘要/Abstract

摘要： 在竖井施工中，截削式掘进机主要靠安装在截割滚筒上的截齿进行破岩，截齿破岩性能的好坏直接决定了掘进机性能的优劣。文章利用有限元方法对单把截齿截割破岩过程进行模拟，分析了截齿在关键参数截割厚度、截割角、齿尖锥角和截割速度下破岩载荷的变化规律|基于正交试验方法，研究此4个关键参数对截齿破岩比能的影响，通过对试验结果进行直观分析和方差分析，得到截齿破岩比能影响因素的主次顺序和截齿破岩参数的最优配置。

Abstract: Abstract: In shaft construction, the cutting-type roadheader mainly relies on the picks installed on the cutting drum to break the rock. The quality of the rock-breaking performance of the picks directly determines the performance of the roadheader. This paper uses the finite element method to simulate the rock-breaking process of a single pick, and analyzes the change law of the rock-breaking load under the key parameters of cutting thickness, cutting angle, tooth tip cone angle and cutting speed; Orthogonal test method to study the influence of these four key parameters on the specific energy of rock-breaking. Through intuitive analysis and variance analysis of the test results, the primary and secondary order of the factors affecting the specific energy of rock-breaking of the pick and the rock-breaking of the pick are obtained. Optimal configuration of parameters. The research results can be used as a reference for improving the rock breaking efficiency of picks.
