Torsional vibration damper design and optimization is essential for engine reliability and performance. Torsional vibration in 4-cylinder engines is inherently high and needs to be treated carefully to avoid engine failures and NVH issues. In addition, torsional vibration, if not controlled, can compromise the engine fuel economy and performance.
The dual torsional damper is used to tune for two frequencies. The objective of this paper is to summarize the optimization steps to maximize the benefits of torsional dampers under the different operating conditions. Taguchi methods have been employed to conduct the analysis.
