Driveline NVH (Noise, Vibration and Harshness) has become an integral attribute in defining how the vehicle NVH performance perceived by the customers in the automotive industry. The driveshaft component design community needs to make sure that the designed driveline system is robust and reliable to achieve the vehicle NVH targets, meanwhile maintains its durability performance. A slip mechanism in the driveline system is needed to accommodate the movements coming from the rear axle and rear suspensions when the vehicle travels on a rough road, or accelerates/decelerates abruptly. One design to accommodate the slip mechanism is to use a press-fitted sliding tube design. Because of its slip mechanism in the tubes, the fluctuation of the contact forces in the tubes, particularly in the vehicle coast down course, the interaction between the tubes becomes a nonlinear contact force phenomenon. This paper uses experimental and analytical linear tools to successfully understand the nonlinear behavior of the sliding tube driveshaft, and prevent a vehicle vibration issue created by the sliding tube driveshaft design.
