STAND FOR DETERMINING MASS AND COORDINATES OF CENTRE OF MASS OF ARTICLE Russian patent published in 2016 - IPC G01M1/12 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement equipment, particularly for measurement of weight characteristics of articles of aircraft and aerospace engineering areas. Test bench consists of table equipped with three mounting spherical supports. Position of spherical support on table can be changed depending on length of measured item. Rotary supports are fixed on table containing rotary device with electric drives. In coordination and installation of article on bench in seats of rotary supports spherical pins are installed. Spherical pins are intended for installation in sockets, when measuring their coordinates with laser coordinate measurement system. Fixation of rotary supports in extreme positions at turn through preset angle is performed by electric interlocking with disconnection of electric or mechanical stop at failure of previous one. Inclination angle value is determined by angle sensors built in struts with platform scales. Post with platform scales is supplied and is able to move along table with subsequent fixation at specified distance. Post with platform scales weighs article and determines reaction of forces acting on support. Post with platform scales has base with supports and rotary wheel for its movement along floor, and can be adjusted in height. Measurement test bench is controlled by computer.

EFFECT: technical result consists in improvement of accuracy of measurements, possibility of adjusting dimensions of bench table by permutation of supports for required size, possibility of storage of stand in disassembled form and short bench preparation for operation.
