Abstract

The invention discloses a low-frequency compensation inertia type actuator and an actuation method thereof. The low-frequency compensation inertia type actuator comprises a stator component, an oscillator component and a low-frequency compensation component attached to the stator component. The stator component comprises magnetic conductive plates, permanent magnets and a shell body. The magnetic conductive plates and the permanent magnets are arranged on the inner wall of the shell body at intervals. The oscillator component comprises a first spring piece, a second spring piece, an actuation rod, a magnetic conductive barrel, a baffle, rubber rings and coils. The low-frequency compensation component with the frequency response characteristic opposite to the frequency response characteristic of the inertia type actuator comprises a low-frequency compensator and a power amplifier. The ladder-like magnetic conductive barrel is connected with the actuation rod in an interference fit mode. The multiple sections of adjacent reversed coils are wound on the outer side of the protruding part of the magnetic conductive barrel. The two rubber rings are installed on the outer side of the downwards concave part of the magnetic conductive barrel. The rubber rings and the baffle jointly clamp the coils on the magnetic conductive barrel.

Description

technical field [0001] The invention belongs to the field of active control, in particular to an inertial actuator with low frequency compensation and an actuating method thereof. Background technique [0002] Vibration generated when mechanical structures work has always been a headache. It is an urgent problem that people need to solve to reduce the vibration generated when the mechanical structure is working. Vibration control is an important branch in the field of vibration engineering, which can be divided into passive control and active control. Vibration active control means that in the vibration control process, according to the vibration signal measured by the sensor, through a certain control algorithm, the actuator is driven to exert a certain influence on the control target to achieve the purpose of suppressing or eliminating vibration. Because of its potential advantages such as good effect and strong adaptability, active control is being used more and more wi...
