Light Truck Driveshaft NVH Analisys and Development Using 6Sigma Tools

This paper presents the method applied in the development and optimization of a powertrain driveshaft for a Light Truck Diesel. The focus of this optimization is to reduce the vibration consequently improve the NVH (Noise and Vibration Harshness) quality of the vehicle. The paper describes the basic 6sigma methodology, inputs required to perform the 6Sigma method, the experimental work required. The experimental results for an optimized version are also presented and compared to the original one.
