N2 - In vibration control with piezoceramics, a high coupling of the piezoelement with the structure is desired. A high coupling improves the damping performance of passive techniques like shunt damping. The coupling can be influenced by a the material properties of the piezoceramics, but also by the placement within the structure and the size of the transducer. Detailed knowlegde about the vibration behavior of the structure is required for this. This paper presents an in-depth analysis of the optimal shape of piezoelectric elements. General results for one-dimensional, but inhomogeneos strain distribution are provided. These results are applied to the case of a longitudinal transducer and a bending bimorph. It is obtained that for maximum coupling, only a certain fracture of the volume should be made of piezoelectric material& L1 - http://www.czasopisma.pan.pl/Content/101489/PDF/20_paper.pdf L2 - http://www.czasopisma.pan.pl/Content/101489 PY - 2014 IS - No 4 EP - 622 DO - 10.2478/aoa-2014-0066 KW - piezoelectric transducer KW - piezoelectric shunt damping KW - piezoelectric energy harvesting KW - vibration damping A1 - Neubauer, Marcus PB - Polish Academy of Sciences, Institute of Fundamental Technological Research, Committee on Acoustics VL - vol. 39 DA - 2014 T1 - Optimal Design of Piezoelectric Actuators for Shunt Damping Techniques SP - 615 UR - http://www.czasopisma.pan.pl/dlibra/publication/edition/101489 T2 - Archives of Acoustics
