Abstract
The purpose of this paper is to provide an overview about rowing clunk on RWD MT transmissions for pick-up trucks through means of sound pressure, case acceleration and torsional vibration.
Intended to identify the proper synchronizer design features necessary for its prevention. This paper will introduce the rowing clunk phenomena and present the driving maneuvers executed to reproduce the noise.
The process of analysis and the phenomena composition based on simulations results, noise measurements and vibration analysis.
The objective is to share with Product Engineering community an approach for Rowing Clunk Noise mitigation on Pick-up Trucks.
