“…Представлена оптимальная конструкция конкретного цилиндрического роликового подшип-ника, полученная с помощью эволюционных алго-ритмов. В работе [6] рассматривается оптимальное проектирование подшипников качения с целью удов-летворения различных ограничений: геометрических, кинематических и прочностных, в то время, как це-левыми характеристиками качества являются срок службы и надежность. Это вызывает необходимость разработки оптимальной методологии проектирова-ния в виде задачи многоцелевой оптимизации.…”

“…Internal parameters include ball diameter (D b ), pitch The purpose of optimization is to evaluate the above mentioned internal geometry to maximize the performance of the bearing. Gupta et al [4] presented the optimization aspects of rolling element bearings by using a non-dominated sorting genetic algorithm (NSGA-II). The design parameters, objective functions and constraints for defining feasible design parameter space considered by the authors are shown below.…”

In this chapter, an effort is made to verify if any improvement in the solution is possible by employing advanced optimization techniques to some of the mechanical element design optimization problems available in the research literature. Seven different mechanical element design problems, like optimization of a gear train, radial ball bearing, Belleville spring, multi-plate disc clutch brake, robot gripper, hydrostatic thrust bearing and four stage gear train, are considered in this chapter for the analysis. The considered problems were solved by using either GA or PSO or by both the methods by the other researchers. These problems are tested by using other advanced optimization techniques such as ABC, DE, BBO and AIA in this book. PSO is applied to the problems to which only GA was applied. The descriptions of different mechanical elements considered in this work are given in the next section. Description of Different Mechanical DesignOptimization Problems Example 1: Optimization of a Gear TrainThis problem is taken from Yokota et al.

“…The optimized bearing yielded better fatigue life as compared to standard catalogues. This study was further evolved [9] to achieve multi-objective optimization of the bearing in terms of static load capacity, fatigue life and elastohydrodynamic film thickness under inner and Article published by EDP Sciences Optimum value of φ for δ ≤ δ lim outer geometric constraints. Angular-contact ball bearings were optimized by Savsani et al [10] for maximum static and dynamic loading ratings and minimum film thickness using a modified particle swarm optimization technique.…”

-Based on the relationships from the ISO 76 standard, this paper optimizes the internal dimensions of tapered roller bearings for maximum static load capacity. A bearing system formed by two identical bearings is assumed, subjected to whatever combination of centred radial and axial forces. It is shown that the static capacity increases linearly with the roller infill, with the ratio of roller length to roller diameter and with the square of the pitch diameter of the roller set. Further, given the ratio of axial to radial force, an optimal contact angle exists which maximizes the static capacity of the bearing pair, regardless of the actual bearing size and ratio of roller diameter to pitch diameter. The optimization procedure can either be used to design custom-made bearings or to pick from manufacturers' catalogues the bearing with the best contact angle for any assigned loading condition.
