Simulation of Actuation and Sensitive Capability of 1-3 Cement Based Piezoelectric Composites

摘要

The simulating software ANSYS is applied to analyze the performance of the 1-3 Piezo-composiites under theσ_3, σ_1 and E_3. Then we get the distribution of the internal stress and strain, sensitivity and activation characteristics. The conclusion is that the ceramic/polymer composites are more sensitive but will lead to stress concentration. While the stress distribution of the 1-3 cement based piezoelectric composites is more uniform so it is be propitious to protect the piezoelectric ceramic rods. The active strain of the 1-3 cement based piezoelectric composites is mainly concentrated on the piezoelectric ceramic rods.
