Based on the existing methodology, the operation modal method by polyreference least-squares frequency domain method is applied. A methodology of rigid-body properties identification of the non-linear stiffness and damping mounting system (the mounting system of powertrain) is introduced and validated. Then the mode parameters and inertia properties of a powertrain rigid-body have been identified by operation modal method. Finally, by the comparison between the results of experiment properties and the result of theoretical calculation, it shows that the mode parameters and inertia properties of powertrain can be identified accurately by operation modal method.
