Parametric Study of DMFW to Reduce Torsional Vibration of Power Train System

구동계 비틀림진동저감을 위한 이중질량플라이휠의 파라미터해석

In this paper, numerical method of evaluating the influence of Dual Mass Flywheel(DMFW) to the torsional vibration of the automotive power train system is developed. And we applied the procedure to the currently being developed HMC's DMFW attached to an FF car to find out the best performance characteristics during the Tip-in/Tip-out operating condition. In doing this we compared the numerical results with the experimental results and Performed Parametric studies. We find out that the torsional vibrational characteristics of power train system can be significantly improved when we optimally choose DMFW, and the developed numerical procedure could be used as valuable tools in developing new DMFW.
