Research on Bandwidth of 1-3-2 Piezoelectric Composite with Multi-Mode

Abstract:

This paper is concerned with the design of a new wideband 1-3-2 piezoelectric composite with multi-mode. The equivalent parameters of 1-3-2 piezoelectric composite with multi-mode are derived from series-parallel theory and uniform field theory. By using numerical calculation, the law of bandwidth varying with the cutting depth is obtained and compared with experiments. The computations show agreement with the experimental results. The results prove that the new wideband 1-3-2 piezoelectric composite with multi-mode can expand bandwidth efficiently, which can be expanded to 28.728 kHz that is 5 times the bandwidth of traditional 1-3-2 piezoelectric composite.
