Problems solved by technology

[0005] For the existing inertial electromagnetic actuator, the electromagnetic force coefficient is small and the working current is large, so that the actuator will generate serious heat when it works for a long time, and an additional heat dissipation device is needed, otherwise the heat will limit the amount that the actuator can generate. Second, due to the lack of structural design, the actuator has a large magnetic flux leakage, which affects the electromagnetic compatibility of the actuator, and the engineering application is limited.

Embodiment Construction

[0033] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0034] like figure 1 Shown is a cross-sectional view of the symmetrical electromagnetic actuator of the present invention, which is a perspective view of the actuator with 1 / 4 cut off. It can be seen from the figure that it includes two electromagnetic structures distributed symmetrically to each other, including two groups A yoke assembly, two sets of armature assemblies and two sets of baffle assemblies. The armature assembly is arranged inside the magnetic yoke assembly, and the magnetic yoke assembly and the armature assembly are connected by a spring piece. In this embodiment, a force transmission frame is a...

Abstract

The invention discloses a symmetric electromagnetic actuator which comprises magnet yoke assemblies, armature assemblies and baffle assemblies. The magnet yoke assemblies and the armature assemblies are connected through leaf springs. The magnet yoke assemblies are movable assemblies. The armature assemblies are static assemblies. The magnet yoke assemblies reciprocate under the action of the armature assemblies to as to control a controlled object. The baffle assemblies are used for limiting the movement of the magnet yoke assemblies. The number of the magnet yoke assemblies is two, the number of the armature assemblies is two, and the number of the baffle assemblies is two. The two magnet yoke assemblies are symmetric, the two armature assemblies are symmetric, and the two baffle assemblies are symmetric. According to the symmetric electromagnetic actuator, actuating force is obviously improved through two sets of electromagnetic structures, and the symmetric electromagnetic actuator is small in size and small in mass and leakage flux.

Description

technical field [0001] The invention relates to an active damping device, in particular to a symmetrical electromagnetic actuator. Background technique [0002] Due to the high reliability of the passive vibration isolation system, and considering the characteristics of the excitation force and other factors, the passive control system is generally used to isolate the vibration source. However, with the continuous development of science and technology, the vibration requirements for the environment and equipment are getting higher and higher, and passive vibration isolation can no longer fully meet people's needs. Therefore, active control of structural vibration through active components has received more and more attention. [0003] Actuator is an important device for active control of structural vibration. Its function is to change the vibration response of the system by applying control force to the control object according to the determined control law. Electromagnetic...
