Description

technical field [0001] The invention relates to a high-frequency electro-hydraulic flutter generator. Background technique [0002] At present, there are mainly three types of vibration equipment, and their performance characteristics are as follows: ①Mechanical type, mainly divided into two types: centrifugal type and direct action type. The frequency range of the centrifugal mechanical vibration device is generally 5-100Hz, and the load is 50-10000N; the frequency range of the direct-acting mechanical vibration device is 1-200Hz, which can obtain a large thrust and a large amplitude. This type of vibrating device has a simple structure and low cost, but the upper limit frequency is low, and is widely used in various low-frequency vibration occasions. ②Electromagnetic type, which can generate complex vibration waveforms, has the advantages of small waveform distortion and large operating frequency range. Due to the limitation of inherent magnetic saturation, it is difficul...
