EXPERIMENTAL STAND FOR TESTING VACUUM SUCTION CUPS OF VARIOUS STRUCTURES AND MATERIALS FOR TORSION IN VARIOUS MEDIA Russian patent published in 2025 - IPC G01M13/00 G01M3/34 G01N19/04 

FIELD: measuring.

SUBSTANCE: invention relates to the field of measuring equipment, namely to the field of measuring friction parameters during mechanical interaction of different materials, and can be used for investigation of friction forces at action of torque on suction cups of different configurations and materials at their fixation on different types of surfaces with specified roughness. Experimental stand for testing vacuum suction cups of various structures and materials for torsion in various environments comprises a rigid frame, on the basis of which the rotary pneumatic motor is installed, on the rotor of which a replaceable rotary disk is fixed, made with possibility of rotation around its axis and equipped with the rotation angle sensor, on the replaceable rotary disk there is a replaceable elastic vacuum suction cup fixed by a rigid fixture on the said rigid frame, stand also has an air ejector which can be fed with air from the main line and has an outlet into the environment, a pressure sensor in the supply main line and a pressure sensor in the evacuated region.

EFFECT: high accuracy of measuring torque due to its controlled variation with time along with estimation of change in the vacuum level with time using a pressure sensor when taking measurements in different media, including multiphase media.
