Driveline shudder is a low frequency vibration caused by axial forces from the inboard constant velocity joints when operating under high torque and angle. A correlated dynamic model representing the shudder problem is described, together with a sensitivity study of the driveline and vehicle parameters that have an influence. The use of this methodology enables driveline arrangements to be investigated at the concept stage, for analysing low frequence NVH (noise, vibration, harshness) phenomena. With regard to the shudder model it has been shown that the natural modes and frequencies of the vehicle system can be calculated, and when some estimates of damping are added then the response of the system to given excitations can be quite accurately calculated.
