RESILIENT SUPPORT WITH ADJUSTER RIGIDITY FOR DYNAMIC TESTS OF TURBINE MACHINE ROTORS AT TEST RIG Russian patent published in 2014 - IPC G01M13/04 F01D25/16 

FIELD: machine building.

SUBSTANCE: resilient support with adjusted rigidity contains a bearing, stator element rigidly secured on the external race of the bearing, casing connected with stator element by means of a radial resilient element of squirrel wheel type, and holder of the radial resilient element. The holder is made with possibility to move along the longitudinal axis of the support on the guides secured on the stator element. The radial resilient element is made in form of cylindrical pins, and holder of the radial resilient element is made with possibility of movement along the longitudinal axis of the support by means of a drive.

EFFECT: invention ensures smooth adjustment of the support rigidity during dynamic test of the turbine machine rotor at test rigs.
