Description of the Problem :
The weight reduction of the drive shaft can have a certain role in the general weight reduction of the vehicle and is a highly desirable goal,
if it can be achieved without increase in cost and decrease in quality and reliability.
It is possible to achieve design of composite drive shaft with less weight to increase the first natural frequency of the shaft and to decrease the bending stresses using
Optimum Design Using Genetic Algorithm
The purpose of using Genetic Algorithm is to minimize the weight of the shaft, which is subjected to the constraints such as
torque transmission,
torsional buckling capacities and
fundamental lateral natural frequency.
The design parameters to be optimized are,
Ply thickness
Number of plies required
Stacking sequence of Laminate
Composite material
Composites consist of two or more materials or material phases that are combined to produce a material that has superior properties to those of its individual constituents.
The constituents are combined at a macroscopic level and or not soluble in each other.
The individual constituents retain those properties
Advanced composite materials are widely used
- High specific strength
- High specific modulus
