To identify the characteristics about the motion of a vehicle, it is often necessary that the inertia properties of the powertrain on the vehicle should be gained, and these values are very important data in the analysis of a vehicle dynamics. But it is not easy that we get the inertia properties of the powertrain for the complexity of the shape. This paper introduces the procedure to obtain the inertia properties using the approach of an experimental modal analysis. The properties of six rigid body modes are obtained by exciting the powertrain fixed in strong steel stands in low frequencies of the band 0 ∼ 40 Hz, and the inertia properties are derived from the values such as frequencies and mode shape vectors about the six rigid body modes. Several mathematical methods based on the theory of modal analysis are used to estimate the inertia properties. It is expected that this type approach will be used in increasing number applications during estimation of inertia properties for vehicle dynamics analysis.
