Research of Rock breaking mechanism of Hydraulic impact rotating jumbolter Based on LS-DYNA

摘要

This paper analyzed the working principle of hydraulic jumbolter, the electronic loads outside of Breakstone, stress distribution status, physical process of brokering rocks, established finite element model of hydraulic impact rotating the jumbolter crashing rock-soil system based on LS-DYNA. Analyzed the effect of brokering rocks when drill moving forward, providing theoretical basis for impact characteristics research.
