Description

Technical Field

[0001] The utility model relates to the technical field of aircraft vibration reduction, in particular to a magnetic suspension vibration reduction device. Background Art

[0002] Shock absorbers include hydraulic shock absorbers, spring shock absorbers and spring steel plate shock absorbers. Most of the existing vibration reduction technologies use spring shock absorbers or shock-absorbing balls to contact with brackets to achieve the vibration reduction effect. However, this contact method will produce friction and affect the vibration reduction effect. The existing vibration reduction technology cannot adjust the filter parameters of the vibration reduction, and is affected by the external environment, such as temperature and air pressure, which causes the vibration reduction effect to deviate from expectations. The existing technology cannot adjust the filter parameters in real time according to demand and cannot achieve real-time vibration reduction. Utility Model Content
