TEST BENCH FOR MEASUREMENT OF STATO-DYNAMIC CHARACTERISTICS OF PHYSICAL OBJECTS Russian patent published in 2015 - IPC G01M1/10 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measurement equipment and can be used for measurement of mass, coordinates of centre of mass and inertia moments of machine-building facilities. The device consists of a dynamometric platform for measurement of mass of an item, a five-component dynamometric element, an oscillation setting device consisting of movable frames connected by hinges and a system of springs connected to the frames; with that, axes of hinges are connected to axes of angle sensors. Besides, the test bench is provided with fasteners providing oscillations only about that axis relative to which inertia moment measurement is made. With that, the five-component dynamometric element consists of four posts of a square section, which are oriented along coordinate axes of the test bench, an upper base on which a physical object is installed by means of a cross piece and a lower base fixed on the dynamometric platform; on edges of each post at the upper base and at the lower base there bonded are strain gauges connected to five bridges for measurement of moments around coordinate axes of the test bench and two lateral forces.

EFFECT: improvement of accurate measurement of inertia moments and coordinates of centre of mass of objects.
