METHOD OF CONTROLLING DRIVING TORQUE MARGIN IN HINGE DEVICES OF LARGE-SIZE MECHANICAL SYSTEMS OF SPACECRAFT ABOVE MOMENTS RESISTANCE Russian patent published in 2016 - IPC G01M13/02 

FIELD: machine building.

SUBSTANCE: invention can be used for determination of driving torque margin in spacecraft hinge devices (HD) above resistive torques both in normal conditions and at extreme temperatures. Implementation of declared method is achieved due to independent from design of large-size mechanical device for determining moment of HD acting on all opening angle of the swivelling device. Independence of swivelling device is provided by HD assembly with all composing HD elements creating additional resistance at its standard opening, for example, by spring drive, such as sections of cable passing by transit through HD (intended for transfer to the spacecraft electric power generated by photo converters, installed on disclosed structural elements of mechanical device and transmission of telemetry signals to control unit of spacecraft), sensors of telemetric monitoring, units for locking HD, units for synchronous opening of separate elements of mechanical device, as well as for delay of opening of separate elements of swivelling device, providing for mechanical opening logic device as whole. HD assembly is performed at simulation of standard disclosure elements of large-sized structure of mechanical device which by weight in tens times less than mass of standard elements, but have seats and surfaces similar to standard ones, therefore additional resistors, acting on hinged device, by weight of movable simulator can be neglected. After determination of HD torque there is possibility of determining margin of driving torque in HD by formula.

EFFECT: technical result consists in improvement of accuracy of determining moments resistance acting in HD.
