Abstract

A centrifugal actuator adopting bevel gear reversing belongs to the field of actuators. The centrifugal actuator is characterized by comprising two centrifugal force actuating units, wherein each centrifugal force actuating unit comprises a brushless direct-current motor and two eccentric block turntables, the eccentric block turntables are coaxially mounted with the motor, and a rotor of the motor is connected with one of the turntables; bevel gears are arranged on both turntables, the bevel gears on the two turntables are both orthogonally engaged with the other bevel gears, and reversing is realized by utilizing the bevel gears; and the motors drive the two eccentric block turntables to coaxially rotate oppositely. Each centrifugal force actuating unit outputs certain amplitude and frequency of force. By regulating the phase difference of the motors in the two centrifugal force actuating units, the actuator is enabled to output given amplitude and frequency of force.

Description

Technical field [0001] The invention relates to a design method of a novel centrifugal actuator, which belongs to the field of actuators. The invention can be applied to active vibration control systems of helicopters and ships. technical background [0002] The vibration active control servo actuation system meets the application requirements of helicopters and ships, and solves the common problem of vibration of the airframe and ships. By installing this control system, the structural vibration of the airframe and ships can be greatly reduced, fatigue failures can be reduced, and the performance of helicopters and ships can be improved. The service life and the reduction of structural vibration can also improve the stealth ability and battlefield survivability of the airframe and ship, and the comfort of the crew has also been greatly improved. [0003] Currently used active vibration control actuation systems mainly include hydraulic actuators, electromagnetic actuators ...
