METHOD FOR GRADUATING MULTICOMPONENT FORCE AND TORQUE SENSORS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G01L25/00 

FIELD: machine engineering.

SUBSTANCE: invention relates to graduation of the force/torque sensors (FTS) with a number of components from one to six. The goal is achieved due to the fact that FTS which mounting flange is connected with cables (at the ends of which there are loads of known mass) through intermediate components (stiffness which is chosen in such a way as to exclude the impact of tensile force on the mounting flange of FTS) moves behind its sensitive flange by the drive system (DS), providing spatial displacement. Thus, the angles of cable inclination and the force or torque acting on the FTS change. The angles of cable inclination are recorded by high-precision angle sensors. In order to tension the cables a drive system can be used instead of loads to ensure the creation of a stable tension force for the cables.

EFFECT: calibration automation of force/torque sensors due to the use of BBS and ensuring the universality of the device, which allows to specify a load in the form of segregates of the main force and torque vector and in all allowable load range of the graduated force/torque sensor, as well as to create complex loading.
