Automotive drive shafts, which transmit power from the transmission unit to the rear axle are in general straight round tubes. An attempt has been made to explore other possible cross-sectional shapes to improve NVH (Noise Vibration and Harshness) performance. The first natural frequency is a very good indicator of the NVH performance. First, finite element based topology optimization and later topography optimizations were tried out. A number of design solutions were obtained from the study and a comparison has been made. A round drive shaft with a bulge at the center has been proposed for stiffenening the drive shaft to improve the first natural frequency.
