Abstract

The invention provides a vibration damping device which comprises an end cover, an outer shell, a main shaft, coils, permanent magnets, magnetic conductive plates, a base and cylindrical springs, wherein the main shaft is positioned in the outer shell; the permanent magnets and the magnetic conductive plates alternately sleeve the main shaft; the same poles of the adjacent permanent magnets are oppositely arranged; the magnetic conductive plates are arranged on both the upper and lower sides of the permanent magnets; the coils and the magnetic conductive plates are oppositely arranged; throughthe winding direction or the wiring design of the coils, the current flow directions of any two adjacent coils can be opposite; the coils are fixed in the outer shell; two ends of the main shaft arecorrespondingly fixed on the end cover and the base; one cylindrical spring is arranged between the end cover and the magnetic conductive plate which is close to the end cover; and the other cylindrical spring is arranged between the base and the magnetic conductive plate which is close to the base. The fatigue strength and the carrying capacity of the whole vibration damping device can be improved, and then the working life of the vibration damping device can be prolonged.

Description

technical field [0001] The invention relates to the technical field of vibration reduction, in particular to a vibration reduction device. Background technique [0002] Vibration control can be divided into passive vibration control and active vibration control from the perspective of external energy demand. Vibration passive control is also known as passive control. Its technology is simple and easy to implement, and it has good economy and reliability. It is widely used in the field of vibration control, but it only has a good control effect on high frequencies. Therefore, active vibration control, that is, active vibration control, becomes particularly important. Because it can adapt to the change of external disturbance frequency and has a good control effect on low frequencies, it has become a new hot spot in the field of vibration engineering. In the active control of vibration, the actuator is one of the key technologies, and the most common method is to install a vi...
