压电相含量和聚合物性能参数对1-3型压电复合材料压电性能影响的有限元模拟
Finite Element Simulation of Effects of Piezoelectric Phase Content and Polymer Property Parameter on Piezoelectric Property of 1-3 Type Piezoelectric Composite
摘 要
采用有限元软件模拟了压电相体积分数，聚合物弹性模量、泊松比对1-3型压电陶瓷复合材料压电性能的影响，并进行了试验验证。结果表明：压电相体积分数为30%~85%时，复合材料的机电耦合系数较高且变化不大；随聚合物弹性模量和泊松比增大，复合材料的串联谐振频率增大，机电耦合系数减小；建立的有限元模型对相对较硬聚合物填充复合材料的串联谐振频率和机电耦合系数的模拟较准确，相对误差均不超过5%，但不适用于相对较软聚合物填充复合材料机电耦合系数的模拟。

Abstract
The effects of volume fraction of piezoelectric phase, and elastic modulus and Poisson's ratio of polymer on the piezoelectric properties of 1-3 type piezoelectric ceramic composite were simulated by finite element software, and the simulation was verified by experiments. The results show that the electromechanical coupling coefficient of the composite was relatively high and changed little when the volume fraction of the piezoelectric phase was 30%-85%. With increasing elastic modulus and Poisson's ratio of polymer, the series connection resonance frequency of the composite increased, and the electromechanical coupling coefficient decreased. The finite element model could accurately simulate the series connection resonance frequency and electromechanical coupling coefficient of the relatively hard polymer filled composites, and the relative error was less than 5%. The model was not suitable for the simulation of the electromechanical coupling coefficient of the relatively soft polymer filled composites.
