The metrological modeling at the certification of weighing system

A.V. Borzenkova, G.A. Cherepaschuk
Annotations languages:

The calculation schemes for determining the gravity center position of aircrafts were refined and the measurement accuracy was estimated, thus the reliability of weighing systems and balance of aircraft were improved. The measurement uncertainty of the gravity center position of aircrafts was evaluated. The metrological modeling concept was considered. Metrological similarity criteria of the model and the object under study were established. The classification was presented and the main steps of building the metrological models as a basis of the modeling process were described. The application of the modeling method at metrological certification of weighing and centering systems was offered.
Keywords: the gravity center, the uncertainty, the metrological certification, the metrological modeling, the weighting and centering system
