Finite Element Analysis of Propeller Shaft for Automotive and Naval Application

The Drive shaft is mainly used for power transmission from the engine to the rear differential. Parts are created by using creo software and the assembled model is exported to analysis Parasolid file and various analysis are performed. Structural analysis of drive shaft to with stand a torque of 10000nm at one where other side is fixed. Use of conventional steel for manufacturing of drive shaft has many disadvantages such as low specific stiffness and strength. Conventional drive shaft is made up into two parts to increase its fundamental natural bending frequency. Two-piece drive shaft increases the weight of drive shaft which is not desirable in today’s market. Many methods are available at present for the design optimization of structural systems and these methods based on mathematical programming techniques involving gradient search and direct search. These methods assume that the design variables are continuous. But in practical structural engineering optimization, almost all the design variables are discrete
