Experimental Validation of the Dynamic Inertia Measurement Method to Find the Mass Properties of an Iron Bird Test ArticleThis presentation describes the DIM method and how it measures the inertia properties of an object by analyzing the frequency response functions measured during a ground vibration test (GVT). The DIM method has been in development at the University of Cincinnati and has shown success on a variety of small scale test articles. The NASA AFRC version was modified for larger applications.
