Title:
SMART ELASTIC BEARING AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/083129
Kind Code:
A1
Abstract:
A smart elastic bearing and a control method. The smart elastic bearing comprises smart polymer material layers (3), metal spacer layers (4) and two joints (1, 2). One of the joints is used for connecting a rotor blade, and the other joint is used for connecting a rotor hub. An external electric field or a magnetic field is applied to the smart polymer material layers. In the elastic bearing, a rubber material which is overlapped with a metal layer in a traditional elastic bearing is replaced with a smart polymer material so as to form a new-type elastic bearing in which metal layers and smart polymer material layers are overlapped with each other. Compared with a traditional elastic bearing using a rubber material, in the working process of a helicopter rotor system, the performance of the smart elastic bearing can be controlled to change by means of changing the physical parameters of the external electric field, the magnetic field, etc. so as to achieve active or semi-active vibration reduction of the helicopter rotor system.
