A Study on the Dynamics of Blast Drilling Feeds Rotary and Pursue Driller’s holder manufactured in Vietnam

Abstract

This article presents the method of establishing the dynamic model
and dynamic equations of the holder of the rotary and pursue
driller, made in Vietnam based on the Lagrange multiplier. The
article determined the cylinder force and the generalized force of
the cylinder, the force applied to the drill in detail. In addition, we
also presented the method of solving the differential algebratic
equations using the acceleration constraints and a stabilization
method according to the sliding mode control principle. The
research results determined the generalized coordinates of the
elements in the chain, from which determined the displacements at
the surveyed points.
