Abstract

The bending stiffness of composite drive shafts is actively controlled by activating optimal sets of shape memory alloy (NITINOL) wires which are embedded near the outer surfaces of these shafts and parallel to their longitudinal axes. With such active control capabilities, the drive shafts can be manufactured from light weight sections without compromising their transverse load carrying capabilities. These features will be invaluable in producing drive shafts for critical applications, such as in helicopters, where high resistance to whirling is of utmost importance. Finite element models are developed to describe the individual contributions of the composite matrix, the NITINOL wires and the shape memory effect to the overall performance of the drive shafts. The theoretical predictions of the models are validated experimentally on a prototype of the NITINOL-reinforced drive shaft.
