| 中文摘要: |
| 精确地控制施加于驱动元件上的预应力,对换能器设计有着重要意义。本文结合我们的课题研究工作,用有限元方法,计算了Ⅶ型水声弯张换能器壳体给驱动元件施加一定预应力时,壳体所需的装配位移的大小,并通过初步实验作了验证。本文的计算及装配方法,可以推广到其它类型的弯张换能器中。 |
| 英文摘要: |
| It is very important for designing underwater flextensional transducers to accurately control the prestress magnitude applied to the active element, the performance of what is determined by the former to a certain extent.On coordination with the author’s research project, the assembly displacement of an underwater flextensional transducer shell, by which is applied prestress to the active element, is calculated with finite element method, and an elementary experiment is performed with a class VII flextensional transducer. The calculating and assembly methods use in this paper may be generalized to other classes of flextensional transducer. |
