A Percussion Performance Analysis for Rock-Drill Drifter Through Simulation Modeling and Experimental Validation

Abstract

The drifter is one of the main components that play a significant role in the percussion capability of the rock drill. The authors of the paper identified the operating mechanism of the drifter and developed an analysis model for the purpose of improving the percussion capability of the rock drill. The authors of this paper also validated the reliability of the analysis model through a comparative study between the analysis results and the results of the experimental tests and utilized the validation results to understand the main factors wielding effects on blow frequency and impact energy.
