Calculus Modelling for Designing Ranging Drum Shearer Variants with Cutting Space Simulation

Abstract

A kinematic-geometric calculus modelling of a handling arm mechanism actuated by hydraulic cylinder is derived and presented in this paper. The calculus model leads to an interactive CAD application of studying and design processing several variants of such mechanism. Special emphasis will be placed upon variants of a mechanism used for driving the mobile arm which positions the cutter-loader’s ranging drum. The mechanism can also be used in other areas of applied mechanics.
