Abstract/Summary Vibration control has been a subject of engineering research for the past few decades. Recently, the use of smart materials-related components for vibration control has become an alternative to traditional vibration control techniques. Vibration control with smart materials have many advantages such as lighter weight, smaller size, flexibility in the structure and lower cost. They are especially suitable where the traditional techniques cannot be applied due to weight and size restriction. The scope of the study is to understand the nature of piezoelectric materials for converting mechanical energy to electrical energy and vice versa. Physical properties of piezoelectric materials for vibration sensing, actuation and dissipation were evaluated. An analytical study of the resistorinductor (R-L) passive piezoelectric vibration shunt control of a cantilever beam was undertaken. The modal and strain analyses were performed by varying the material properties and geometric configurations of the piezoelectric transducer in relation to the structure in order to maximize the mechanical strain produced in the piezoelectric transducer. Numerical modelling of structures was performed and field-coupled with the passive piezoelectric vibration shunt control circuitry. The Finite Element Analysis (FEA) was used for the analysis and optimal design. Experiments with the passive piezoelectric vibration shunt control of beams were also carried out and the results compared to the analytical and computational work described above.
