OSCILLATION LIMITING UNIT, AND DEVICE, STRUCTURAL SEGMENT FOR BUILDING BLOCK AND WIND-DRIVEN POWER PLANT WITH OSCILLATION LIMITING UNIT Russian patent published in 2017 - IPC F16F15/121 F03D13/20 F03D80/80 

FIELD: physics.

SUBSTANCE: unit (100) has a support structure (150) with a base plate, a pendulum system (101) with a pendulum weight (110) and a suspension system (120) for suspending a pendulum weight (110) on the support structure (150). The suspension system has a suspension (130) of the pendulum weight travelling in the direction of suspended axis, where the pendulum weight is fixed on the support structure by means of a hanger (170). Thereby the suspension system (120) has a plurality of pendulum spring elements (140) extending in the direction of suspended axis ("НА"), and the pendulum spring element (140) of the plurality of pendulum spring elements has a spring (141) designed as a compression spring and equipped with a spring plate (181 ). The hanger (170) of the suspension (130) of the pendulum weight has a swivel head (131) which is fixed to the support structure and has a pendulum bearing formed as a sliding bearing. The pendulum spring element (140) has a spring holder which is adapted to change the adjustment of the spring length, i.e. for adjustment of the spring force. The spring plate (181) is, on the one hand, placed at a distance from the base plate, which, on the other hand, has a support profile (182) which carries a variably controlled adjustment mechanism (180), wherein the support profile (182) has an end stop and an actuator.

EFFECT: reliable decrease of the oscillation amplitude.
