The main objective of this project is to design analyses and optimize a composite gear box using modeling and analyzing software’s to reduce the weight and improve its performance. A gear box is used to vary the speed of a system which is run by using a prime mover such as motor, engine. For attaining different speed these types of gearboxes are used.

In recent days they are using hardened steel or iron in the manufacture of gears that are used in the gearbox. These types of materials have high mass and stress. This causes a poor performance of the system. To improve the performance of the system, there must be a minimum stress and mass in the transmission system. Some composite materials can satisfy these conditions.

A gearbox is designed with various design parameters and is modeled using modeling software. The various stress, displacement and strain for the gear box is identified by applying various materials using analyzing software. by using an optimization technique, suitable material for the gearbox is identified and applying it to the existing gearbox for comparison of the lifetime and performance.
