The invention discloses a silencing vibration stopper and an adjusting method thereof, and belongs to the technical field of
vibration control. The silencing vibration stopper comprises a belleville spring set, a spring oscillator unit, a lead screw adjusting mechanism and a
frequency modulation control system; the spring oscillator unit comprises a top plate, a spring oscillator and a bottom plate. The belleville spring set is arranged between the spring oscillator and a first supporting column set and a second supporting column set between the spring oscillator and the top plate and the bottom plate in a sleeving mode. The lead screw adjusting mechanism comprises an adjusting lead screw, and the adjusting lead screw can penetrate through the top plate and the spring vibrator and then is connected with the middle connecting column. The spring oscillator unit is provided with an acceleration sensor group; the
frequency modulation control system collects vibration signals in real time through the acceleration sensor set, the lead screw adjusting mechanism is driven through a
PID control algorithm, the pre-tightening force of the belleville spring set is dynamically adjusted, and the
vibration absorption frequency is adjusted. Dynamic adjustment of the inherent frequency can be achieved, the structure is convenient and fast, the adjustment precision is high, the response speed is high, and the requirement for narrow-frequency-domain vibration suppression is met.
