Embodiment Construction

[0015] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0016] The inertial actuator device according to the present invention consists of four parts: a static force balance device, a vibrator limit device, a force output device and a frame. The static balance device consists of a handle, an upper cover and a spring, which are used to counteract the gravity of the exciter so that the device can be installed at any angle. The limiting device of the vibrator is composed of an upper ring, an upper leaf spring, an upper plate, a limit screw, a lower plate, a lower plate spring and a lower ring. The exciter is installed between the upper plate spring and the lower plate spring, and the limit screw Used to check whether the exciter is in the equilibrium position. The force output device is composed of an adjusting screw and a base, one end of the adjusting screw is connected wit...

Abstract

The invention relates to an inertial-type actuator which comprises a static balancing device, a vibration exciter limiting device, a force output device, a frame and a vibration exciter, wherein the static balancing device, the vibration exciter limiting device and the force output device are fixed on the frame, the static balancing device is connected with the vibration exciter and is used for offsetting the gravity of the vibrator exciter when the inertial-type actuator is installed on the surface of a structure, the vibration exciter limiting device is connected with the vibration exciter and is used for limiting the radial displacement of the vibration exciter, and the force output device is connected with the vibration exciter and is used for transmitting the output force of the vibration exciter to the structure when the inertial-type actuator is installed on the surface of the structure. According to the structure of the inertial-type actuator, an inertial mass type electromagnetic vibrator can be installed on the surface of the structure in any angle, in addition, the equilibrium position of the vibration exciter can be conveniently adjusted, and therefore the inertial mass type electromagnetic vibrator is enabled to effectively be a secondary source in active control.

Description

technical field [0001] The invention relates to the field of active control, in particular to the field of active control of structure vibration / radiation sound, in particular to an inertial actuator. Background technique [0002] Structural vibration / radiated sound exists in all aspects of life. Generally, passive control techniques such as sound insulation and sound absorption are not effective at low frequencies. Therefore, active control technology has become the main method to control the vibration / radiated sound of structures at low frequencies. The active control technology of structural vibration / radiated sound refers to the use of secondary vibration sources to stimulate anti-phase vibration of the structure to offset the primary vibration of the structure, thereby reducing the vibration / radiated sound of the structure. Actuators are one of the important issues in active control technology. Reasonable actuator design or selection can directly improve the control ...
