RESILIENT SUPPORT WITH ADJUSTABLE RIGIDITY FOR BENCH DYNAMIC TEST OF TURBOMACHINE ROTORS Russian patent published in 2016 - IPC F01D25/16 

FIELD: engines and pumps.

SUBSTANCE: invention relates to design of elastic supports with variable compliance, used in bench dynamic tests of turbomachine rotors. In the elastic support with adjustable rigidity for bench dynamic test of turbomachine rotors containing bearing fitted on the tested shaft (rotor), stator element rigidly fixed on the external ring of bearing case connected with the stator element through the radial resilient element of "squirrel cage" type, mandrel of radial resilient element made with possibility of movement along the longitudinal axis of the support along guides at one end fixed on the stator element, on the bearing housing there are through holes in which guides are installed with a gap.

EFFECT: higher reliability of support during tests.
