Optimal Design of a Heavy Duty Helical Gear Pair Using Particle Swarm Optimization Technique

A helical gear pair of a heavy duty gear reducer is considered for the objective of minimum volume, since the most power transmission systems require low weight energy efficient and cost effective system elements. The various factors for sizing and strength of gears are computed for gear geometry parameters using DIN standard. The formulation of the constrained non-linear multi-variable optimization problem with derived objective function and constraints is presented. The solution is attempted using Particle Swarm Optimization (PSO). The results achieved are satisfactory and helps designer to employ for minimum material and cost by fulfilling the strength and performance requirements.
