Abstract

The invention relates to the technical field of vibration exciters, and provides a flexible vibration exciter, which includes a bracket and an elastic vibration excitation component. The bracket has a first installation end and a second installation end; the elastic excitation assembly includes a first dielectric elastomer driver, an elastic structural member and a connection assembly, one end of the first dielectric elastomer driver is connected to the first installation end, and, One end of the elastic structural member is connected to the second installation end. In the initial state, the first dielectric elastic body driver, the connection assembly and the elastic structural member are in static equilibrium at the first mounting end and the second mounting end of the bracket. When the AC voltage is connected to the front and back of the first dielectric elastomer driver, the stiffness of the first dielectric elastomer driver is changed, and the connecting assembly is displaced, that is, between the first dielectric elastomer driver and the elastic structural member Vibration occurs, the working principle of the flexible vibrator of the present application is different from that of the existing mechanical vibrator, and the overall structure is simpler.

Description

Flexible shaker technical field [0001] The present invention relates to the technical field of vibration exciters, and in particular provides a flexible vibration exciter. Background technique Vibration exciter (vibration exciter) is attached to certain vibrating machinery and equipment to generate excitation force The device is an important part that drives and utilizes mechanical vibration. The vibrator can make the excited object obtain a certain form and size of vibration to conduct vibration and strength tests on objects, or to calibrate vibration testing instruments and sensors. The exciter can also To excite the components to form a vibrating machine, to realize the conveying, screening, compacting, forming and tamping of soil sand and gravel of materials or objects Solid work. [0003] However, the existing vibration exciter is mostly mechanical, that is, its working principle is mostly connected by a mechanical mechanism to achieve, Therefore, the struct...
