Vibration in a driveline is presented in this paper. In the experiment, the rear subframe
and propeller shafts and axle were composed and mounted with rubber each other. For applying the
vibration input instead of the torsional vibration effect of an engine, the shaker was taken. In
particular, torsional vibration due to fluctuating forced vibration excitation across the joint between
driveline and rear subframe was carefully examined. Accordingly, the joint response was checked
from experiments and the FE-simulation using FRF (frequency response function) analysis was
performed. All test results were signal processed and validated against numerical simulations. In
present study, the new test bench for measuring the vibration signal and simulating the vehicle
chassis system was proposed. The modal value and the mode shape of components were analyzed
using the model to identify the important components affecting driveline noise and vibration. It
could be reached that the simplified test bench could be well established and be used for design
guide and development of the vehicle chassis components.
