摘要:
偶极声波测井仪器接收换能器的核心是圆形四叠片结构的压电振子。前人的研究主要集中在圆形三叠片结构,对第4层非金属圆盘的影响没有涉及。通过对比圆形三叠片压电振子的数值解与解析解,验证了用有限元方法进行数值模拟的正确性,考察了非金属圆盘的几何结构对压电振子谐振频率的影响,以及在圆盘边缘施加不同边界条件时,压电振子谐振频率的变化。模拟结果显示,在不同边界条件下,谐振频率变化较大。夹支边界对应的谐振频率最低,自由边界对应的谐振频率最高。圆盘几何尺寸对基频影响较大,圆盘直径越小、厚度越大基频也越大。
Abstract:
The fourlayer circular vibrator is the core of acoustic dipole transducer. Previous studies are mainly focused on circular threelayer structure;few references involve the effect of the fourth layer non metal plate. First we compare the numerical solution of a threelayer circular vibrator with the analytic solution to verify the finite element method. Then, by FEM method, we investigate the effect of different dimensions of non metal plate on resonance frequency and resonance frequency changes with different boundary conditions impacting on the plate edge. The results of simulation indicate that the resonance frequency varies with different boundary conditions. The frequency corresponding to free boundary condition is the highest, while the frequency related to clamped boundary condition is the lowest. The dimension of the plate also has great impact on the frequency. The frequency increases with the decreasing of plate diameter or increasing of plate height.
