Identification of dangerous hoisting loads based on vibration characteristics
Published online on June 29, 2016
Abstract
The dynamical behaviors of steel ropes and containers caused by different dangerous hoisting loads are theoretically and experimentally investigated to improve the hoisting safety in coal mines. Subsequently, the identification method is studied. The modal analysis technique based on Ritz Series and the Dempster–Shafer evidence theory is respectively employed during the study on vibration and identification. The vibration characteristics are apparently different with different categories and severities of dangerous loads. The different dynamical behaviors could be used as the basis of identification. The Dempster–Shafer evidence theory efficiently reduces uncertainty during the identification process of dangerous hoisting loads. Outcomes of this study might make a significant contribution to the hoisting safety in coal mines.
