Single-degree-of-freedom passive non-contact vertical type eddy current magnetic damping generator

Abstract

The invention discloses a single-degree-of-freedom passive non-contact vertical type eddy current magnetic damping generator. The single-degree-of-freedom passive non-contact vertical type eddy current magnetic damping generator comprises a main shaft, a guide shaft, an upper top board, an upper end cover, a lower end cover and a lower bottom board, wherein the upper top board, the upper end cover, the lower end cover and the lower bottom board are sequentially arranged up and down; the main shaft is fixedly connected with the lower bottom board and sequentially penetrates through the lower end cover and the upper end cover; the main shaft is sleeved with a conductor pipe; the conductor pipe is fixedly connected with the upper end cover and the lower end cover; a permanent magnet is arranged between the conductor pipe and the main shaft; a gas gap is formed between the conductor pipe and the permanent magnet; and the upper end and the lower end of the permanent magnet are fixed to themain shaft. The single-degree-of-freedom passive non-contact vertical type eddy current magnetic damping generator is an independent modular device capable of providing damping, during usage, only thelower bottom board of the device is fixedly connected with a base, the upper top board of the device is fixedly connected with a vibrating body through a top board, and at the moment, when the vibrating body and the base move relatively, the device can generate the damping effect.

Description

technical field [0001] The invention relates to the field of single-degree-of-freedom vibration control in the vertical direction, in particular to a vertical eddy current magnetic damping generator for non-contact vibration control using the magnetic damping effect. Background technique [0002] Vibration is a very common and unavoidable phenomenon in mechanical equipment. If the vibration exceeds a certain range, the equipment will generate large noise, which will have adverse effects on the surrounding environment, and will seriously affect the performance of the equipment and shorten its service life. Related components fail prematurely. Therefore, vibration reduction is essential in mechanical equipment. [0003] In mechanical devices such as general engines, damping materials, hydraulic dampers, gas dampers, etc. are usually used to reduce vibration. However, damping materials such as rubber have disadvantages such as large space occupation, inconvenient installation...
