Abstract
Based on the smart spring’s active vibration method, the micro-displacement of piezoelectric ceramic actuators is generated by applying controlled voltage and alternation of the impedance characteristics—no complex displacement amplifying device and high driven voltage are required. A device with active vibration reduction was designed according to the concept of a smart spring. This device is compact in structure, easily assembled by friction blocks and with convenient adjustment of clearance. An excitation test using a single-stage smart spring vibration reduction was carried out, which verified the feasibility and validity of the smart spring’s vibration reduction performance. The experiment and the theoretical analysis described in the paper presents the value of the design of the smart spring system.
