Optimum design of straight bevel gears pair using evolutionary algorithms

Advanced design optimization on straight bevel gears pair based on nature inspired algorithms

“…Designing a bevel gear pair is a tiresome job, as it involves various factors such as gear geometry, heat treatment and manufacturing, while accounting for practical considerations such as high strength, high accuracy, low noise and low volume. Low volume gears offer a considerable decrease in energy consumption [2]. The stipulations of AGMA are used for standard mechanical constraints.…”

“…He took module, face width and face width factor as design variables subject to normal mechanical constraints. Zolfagari et al [2] optimized volume of straight bevel gear governed by the AGMA instructions, through SA and GA. Nevertheless, Zolfagari et al [2], had not considered an important design variable, namely, the shaft diameter and also certain other critical mechanical constraints.…”

“…Zolfagari et al [2] optimized volume of straight bevel gear governed by the AGMA instructions, through SA and GA. Nevertheless, Zolfagari et al [2], had not considered an important design variable, namely, the shaft diameter and also certain other critical mechanical constraints. To narrow down the gap identified in Zolfagari et al [2], an additional critical design variable and constraints are introduced in this paper.…”

“…To tide over these, in this paper, besides considering regular constraints, one more design variable and six other mechanical constraints are added. Certain other equivalent constraints in Zolfagari et al [2] are replaced by a single inequality constraint to make the work simpler. This research is based on Zolfagari et al [2], but this paper bridges the gap identified in their work, by introducing certain essential additional design variable and constraints.…”

“…Root not cut-In this research, prevention of undercutting is countered by considering only one equation. Zolfagari et al [2] did consider this constraint, but they addressed the problem with six equivalent constraints. But in this research, the task is simplified, by using a single equivalent constraint, in order to provide the designer an acceptable solution in less time.…”
