Introduction
Power-train NVH is a vast area lots of related publication can be seen in this area. The power-train system of a
vehicle typically includes the engine and transmission (power plant), driveline, axle, induction and exhaust
subsystems and shown in Figure 1. From the literature one can find that for addressing issues with low to mid
frequency vibrations almost all the major automotive industries were relaying with FEM and BEM based approach
along with some 1D analysis approach. For high frequency analysis (> 3000Hz) SEA (statistical energy analysis)
has been used. In that process FEM models has been analyzed for predicting the power-train bending modes, modal
