FIELD: measuring devices.
SUBSTANCE: invention is related to the field of devices for measuring mechanical quantities, in particular, to devices for measuring mass, coordinates of the centres of mass and moments of inertia of full-scale aircraft of their elements. A stand is proposed for measuring the mass, coordinates of the centres of mass and moments of inertia of products, equipped with a five-component dynamometric element (FDE), a three-axis angular acceleration sensor (TAAS), rotation angle sensors and dynamometers. The device comprises a frame, a swivel frame with a rotation angle sensor placed on it and connected to the frame by a swivel assembly and a system of springs to ensure successive oscillations around three orthogonal axes of the loading platform with the product, and the weight frame connected to the rotary frame by means of dynamometers. In addition, the stand is equipped with a mechanism for turning and swinging the load platform, placed on the weight frame and connected to it by means of support legs and springs, and consisting of four connecting plates and a table with the TAAS placed on it and connected to the load platform through the FDE.
EFFECT: expanding the range of width and depth of products, the mass-inertia parameters of which are measured on the stand without reducing the measurement accuracy.
