| 摘 要： | 用ANSYS有限元软件对纯压电陶瓷(PW)及0-3型水泥基压电复合材料(PCM0)依次进行静力、模态、谐响应及瞬态动力特性力-电耦合场分析,并以PCM0半径(Rc)和厚度(Hc)为变量对进行材料量优化设计。相比PW,PCM0垂直于极化方向的电位移增大10.9%,使压电应变常数增大;响应频率减小,呈稳态响应特性;水泥掺入对PCM0迟滞效应影响可接受。PCM0最优材料用量对应的Rc、Hc分为5.1mm、0.76mm。

| Abstract: | The piezoelectric coupling analysis of piezoelectric ceramics wafer(PW) and cement-based piezoelectric composite wafer(PCM0) on static analysis, modal analysis, harmonic analysis, and transient dynamic analysis was systematically studied by finite element numerical simulation, respectively. Furthermore, the material usage optimization of PCM0 was carried out with wafer radius(Rc) and density(Hc) as the design parameters. The results show that the maximum displacement vertical to polarization direction of PCM0 increases 10.9% compared with those of PW, indicating that the piezoelectric strain constant of PCM0 is increased; Its response frequency falls down and exhibits steady response characteristic. It can be acceptable for the impact on hysteresis effect of PCM0 with cement mixing. The optimal material usage for PCM0 wafer design is Rc of 5.1 mm, Hc of 0.76 mm, respectively. |
