Estimation of inertial characteristics for non-rigid basic part

This paper provides an approach for estimation of mass and coordinates of the center of mass for basic part possessing of insufficient natural rigidity. Using of such objects in dynamic testing trials for determination of inertial characteristics imparts them feature of independent oscillating system attached to measuring bench. So in this way dynamic inaccuracy of measurement is increasing. It is suggested to test objects in the field of centrifugal forces that are constant in magnitude and in direction by using well-known method for determination of rotor disbalance magnitude and position.

Keywords: mass, coordinates of the center of mass, disbalance, time lag, phase.
