Multi-Objective Optimization of Two-Stage Helical Gear Train Using NSGA-II

Abstract: Gears not only transmit the motion and power satisfactorily but also can do so with uniform motion. The design of gears requires an iterative approach to optimize the design parameters that take care of kinematics aspects as well as strength aspects. Moreover, the choice of materials available for gears is limited. Owing to the complex combinations of the above facts, manual design of gears is complicated and time consuming. In this paper, the volume and load carrying capacity are optimized. Three different me… Show more

“…Load carrying capacity-It is a functional characteristic of the gear. In this work, the optimum values for minimum volume obtained in this research are used to find the load carrying capacity at both the stages [15]. The constraint condition is formulated in such a way that, this calculated value should be more than the minimum allowed load carrying capacity of the gear [29].…”

“…The optimization results ought to be a set of optimal solutions rather than an optimal solution. This set is known as the Pareto optimal set, and its corresponding tradeoff in objective space is known as the Pareto optimal frontier, which is made up of the Pareto optimal points (Sanghvi et al 2014;Huang et al 2007;Hu and Yu 2009). Designers could select an optimized scheme which satisfies the requirements of all disciplines from the Pareto optimal set.…”
