An Optimal Design Methodology of Tapered Roller Bearings Using Genetic Algorithms

Design optimization of an angular contact ball bearing for the main shaft of a grinder

“…In Eq. (13), h denoted an oil film thickness at a contact point between a ball and raceway, and values with regard to the surface finish of the raceways (f races ) and surface finish of the balls (f balls ) were set to 0.175[μm] and 0.0625[μm], respectively. If the film parameter value was larger than or equal to 3, there was a sufficient oil film thickness and thus surface friction would not occur [22].…”

“…Lin [12] implemented design optimizations for deep groove ball bearings to maximize their dynamic load rating and used differential evolution combined with real-valued genetic algorithms as an optimizer, comparing its performance with those of existing binary-code genetic algorithms. Tiwari, Sunil, and Reddy [13] obtained optimum designs to maximize the dynamic load capacity for tapered roller bearings. Waghole and Tiwari [14] maximized the dynamic capacity of needle roller bearings and used an artificial bee colony algorithm (ABCA), a differential search algorithm (DSA), a grid search method (GSM), a hybrid method combining the ABCA and GSM, and a hybrid method combining the DSA and GSM as optimizers.…”

“…Additionally, [5,9,10,13,14] included contact stress, [8] included film thickness, and [11] included friction. However, a comprehensive design problem formulation of this study took into account the radial stiffness and axial stiffness due to simultaneously imposed radial and axial loads in addition to all of the design requirements considered in prior studies.…”

Optimal design of paired tapered roller bearings under centred radial and axial static loads

“…Papers dealing with the optimization of bearing features have appeared only lately, aimed at maximizing one or several performance properties of ball bearings [5][6][7][8][9][10][11], cylindrical roller bearings [12,13] and tapered roller bearings [14][15][16][17][18][19].…”

“…Though interesting for the potential of improvements it shows, Wang et al's paper [17] does not provide details on the optimization method behind the model and little can be taken away from the published results apart from the specific example presented. Two comprehensive contributions to the optimal design of tapered roller bearings have recently been published by Tiwari et al [18,19]. These two papers contain also excellent reviews of the technical literature on rolling bearings and the various optimization methods applied so far to bearing design.…”
