FEA is an important tool for doing

FEA is an important tool for doing NVH analysis. But conventional FEA procedures alone cannot predict how
much noise a power-train will generate or which structural path is critical for noise reduction. Using FEA, another
analysis procedure can be used for NVH analysis is transfer path analysis (TPA) this procedure gives clear
information on which structural path contributes how much noise. In [6] NVH performance of the vehicle was
predicted for early design stage of a vehicle, simulation of interior noise for assessment and enhancement of the
noise, vibration and harshness (NVH) was carried out. They have used a hybrid TPA technique. For Hybrid TPA
they had used simulated excitation force as the input force, which excites the flexible body of a vehicle at the mount
points, while traditional TPA uses the measured force. This simulated force was obtained by numerical analysis of
the finite element (FE) model of a power-train. Interior noise was predicted by multiplying the simulated force by
the vibro-acoustic transfer function (VATF) of the vehicle. The VATF is the acoustic response in the compartment
of a vehicle to the input force at the mount point of the power-train in the flexible car body. The trend of the
predicted interior noise based on the hybrid TPA correlates well to the measured interior noise, with some difference
may be due to small experimental and simulation error.
