“…The radial stiffness of ball bearings mainly determines the bending vibration of the ball screw. In the study of the axial and torsional vibration of the ball screw, the radial stiffness of ball bearings is normally neglected [5,17,18]. Inspired by those studies, the radial stiffness of ball bearings is not considered in the model here.…”

“…It has become mainstream to consider the effect of ball screw feed drives in the study of dynamic characteristics of stages. For instance, taking the stiffness of the ball bearings, the screw shaft, and the screw-nut interface into account, the vibration characteristics of the stage were investigated by means of lumped-parameter method [2][3][4][5]. Besides, considering the effects of the preload and rigidity of linear guide modules, the vibration characteristics of the stage were researched using the FE method [6][7][8][9].…”

An analytical modeling approach for ball screw feed drives is proposed to predict the dynamic behavior of the feeding carriage of a spindle. Mainly considering the rigidity of linear guide modules, a ball-screw-feeding spindle is modeled by a mass-spring system. The contact stiffness of rolling interfaces in linear guide modules is accurately calculated according to the Hertzian theory. Next, a mathematical model is derived using the Lagrange method. The presented model is verified by conducting modal experiments. It is found that the simulated results correspond closely with the experimental data. In order to show the applicability of the proposed mathematical model, parameter-dependent dynamics of the feeding carriage of the spindle is investigated. The work will contribute to the vibration prediction of spindles.

“…Sensitivity analysis, within the scope of modelling, means different things to different people (see, e.g., Ferreira 2010; Mang et al 2011;Keitel et al 2011;Vaitkus 2011;Zhou et al 2011). The basic measure of sensitivity is given by Spearman rank-order correlation (Kala 2005;Idoro 2012;Rafiei et al 2012).…”

Abstract. Researches in the field of economy of control of mining processes of minerals are continually met with a number of unsolved and newly arising problems. New deposits of brown coal are located at greater depths than before and are more difficult to mine. Problems in the field of rock mining stem from the greater diversity of rocks in mining, and it results in more difficult mining conditions. On the other hand, even greater demands are made to decrease the economic demand of mining. Current research is aimed at the most optimal utilization of energy provided on the bucket wheel of excavators, such that the energy demand of the mining process decreases, whilst preserving maximum performance. These requirements place greater demands on the precision of planning of mining and maximum economic efficiency. The presented article illustrates the possibilities of the utilization of Sobol sensitivity analysis during the investigation of the influence of the parameters of mining processes on tangential digging forces. Analyses are carried out for the mining process of bucket wheel excavator SchRs 1320. For purposes of the study, detailed measurements of operational parameters were performed on the excavator during a whole work cycle.
