Application of Genetic Algorithm to Optimize Worm Gear Design for Minimum Centre Distance

A gear transmission problem is one of the most complex optimization problems because of relationship between different variables. A gear design require the designer to compromise many design variables; i.e. continuous, discrete & integer variables in order to determine best performance of gear set. Numbers of conventional methods are available for solving different types of optimization problems. But due to their complexity and convergence problem these methods are not able to give optimal solution. Therefore researchers are now going to use evolutionary techniques. Genetic Algorithm is one of such technique. A non-conventional algorithm namely Genetic Algorithm is presented for optimization of worm gear mechanism with respect to specif ied set of constraints. The Genetic Algorithm is an eff icient search method which is inspired from Darw in’s concept of selection process to explore a given search space.
