Vibration characteristics of two damper in CV joint drive shaft

초록

A harmonic force of engine excites drive shaft and generate resonance. Dynamic vibration absorber (DVA) is installed for reduction of shaft's vibration. Single DVA is generally used for vibration reduction. Single DVA's effect has limitation about mass, stiffness and damping. To get better vibration reduction, the multi DVA connected three or more single DVAs is more effective than single DVA. But if single DVA connected three or more, DVAs coupled other parts. So, this study confirms two DVA connected two single DVAs. This paper compares single DVA and two DAV. Experiment was performed in zig for measuring frequency response function (FRF). To verify vibration and interior reduction while driving, accelerators and microphone were installed in steering wheel, seat rail and driver's ear position. © Proceedings of 2020 International Congress on Noise Control Engineering, INTER-NOISE 2020.
