Analysis of cutting picks trajectory and cutterhead vibrations of roadheader with use of high-speed cameras

Abstract

In order to identify the behavior of cutting picks during the process of mining with the use of a roadheader's cutterhead, an optic system has been employed. The main elements of the system were high-speed cameras. In conjunction with TEMA Motion 3D software (which is designed to analyze movement based on images registered in videos), this allowed for a detailed analysis of the trajectories of the boom, cutterheads, and cutting picks during the process of cutting. This article presents the process of conducting measurements as well as the results of a comparative analysis of the boom vibrations and movement trajectories of cutting picks on the cutterhead for selected cut types: progressive and degressive.

Vibration identification of the roadheader cutting head using high-speed cameras

“…In the Department of Mining Mechanization and Robotisation of the Silesian University of Technology, mining machines, i.e. scraper conveyors [13,14] and a roadheader [15], were tested in laboratory conditions. This article presents selected roadheader test results with respect to the analysis of movement and vibrations of its main components in operation.…”
