FIELD: physics, measurement.
SUBSTANCE: invention is related to testing equipment, in particular, to benches for testing of machine parts and mechanisms under effect of dynamic loads. Test bench for creation of controlled dynamic loads has in its composition loading hydraulic cylinder, working cavities of which are connected to electrohydraulic transducer, and detector of loading hydraulic cylinder stem displacement. At that bench is additionally equipped with load detector, which is installed in kinematic circuit with tested object, equipped with programmable control device, which is connected via digital-analog transducers to the first and second electronic controllers, outlets of which are connected to electrohydraulic transducer. Mentioned displacement detector is connected to the first electronic controller and via analog-digital transducer - to programmable control device, and load detector is connected to the second electronic controller and via the second analog-digital transducer - to programmable control device.
EFFECT: higher accuracy of measurements.
