Bistable nonlinear vibration absorber for inhibiting micro-amplitude vibration

The invention discloses a bistable nonlinear vibration absorber for inhibiting micro-amplitude vibration, which is characterized in that a mass block is fixed on a beam through a bolt, one end of the beam is clamped and fixed by a fixed clamp and a first fixed clamping plate through a first bolt, and the other end of the beam is clamped and fixed by a sliding clamp and a second fixed clamping plate through a first bolt; the fixed clamp is fixed to the linear sliding groove plate through a second bolt, and the sliding clamp can move back and forth in the linear sliding groove plate. A spiral micrometer head is fixed in a check block through a fixing nut, the check block is installed on the linear sliding groove plate, and a push rod of the spiral micrometer head abuts against the sliding clamp. The broadband vibration absorber can effectively suppress micro-amplitude vibration, can effectively absorb broadband vibration, and is simple in structure, easy to implement and wide in application range. 本发明公开了一种抑制微幅振
