The invention relates to a modular adjustable-parameter
dynamic vibration absorber and a parameter presetting method thereof, and relates to an adjustable-parameter dynamic vibration absorbing device. The
dynamic vibration absorber comprises a base, a linkage seat, hinge supports, lever lower arms, lever
upper arms, a fine-tuning spring, guide rails, a
mass block, a tray, main springs, a fine-tuning
damper, a main
damper, and parallel holes. The base and the linkage seat are connected through bolts, and the hinge supports are connected with the linkage seat through bolts. The springs and the dampers are in
modular structure. The lever lower arms are connected with the lever
upper arms through connecting shafts. The tray is hinged with the lever
upper arms through connecting blocks and connecting shafts. The
mass block is fixed on the tray through locking bolts; sliding channels are reserved on the tray, a sliding pair can be formed by the sliding channels and the guide rails, and the tray is connected with the main
damper and the main spring. The linkage seat is connected with the main damper and the main spring, and the tray is provided with parallel shafts. The invention aims to overcome defects of unexpected portability, unadjustable parameters and the like of existing dynamic vibration absorbers.
