Description

technical field [0001] The invention relates to the field of vibration damping equipment, in particular to a six-sided cylindrical fractional slot concentrated winding type active vibration absorber. Background technique [0002] The current active dynamic vibration absorber is to add a substructure (ie the vibration absorber) to the target vibration system (ie the main system). By selecting the appropriate substructure structure, dynamic parameters and coupling relationship with the main system, Change the vibration regime of the primary system to reduce the forced vibration response of the primary system in the expected frequency band. Usually, a dynamic vibration absorber has only one resonance point, that is, it only acts as a vibration absorber at a certain natural frequency, and its adaptability is not strong when the vibration situation is complex and changeable. [0003] The design of the active dynamic vibration absorber is based on the traditional passive dynamic ...
