摘要
利用ANSYS有限元软件数值模拟了小井眼中声波测井偶极换能器在空气中的振动,结果显示,换能器的基频受边界条件的影响,钳定或简支后基频比自由状态下明显降低;同种边界条件随着载荷位置外移,基频也会下降。
ANSYS finite element software is used to simulate the vibration of acoustic dipole transducer in the air. The result shows that fundamental frequency is affected by the boundary condition.It decreases when the boundaries are clamped or simply supported. And it also decreses when load position is moved outside under the same boundary condition.
