| 摘要: |
| 对Spherical-cymbal换能器的静水压性能进行了研究。采用有限元法计算了该换能器在静水压下的米塞斯等效应力，找出了其所能承受的极限静水压。研究了金属端帽几何尺寸及端帽材料对Spherical-cymbal换能器耐压极限的影响，结果表明，空腔深度、端帽厚度及端帽材料对该换能器耐压性能影响显著；对比研究表明，参考尺寸下的Spherical-cymbal换能器比传统Cymbal换能器具有更高的耐压极限。 |

| Abstract: |
| The hydrostatic pressure tolerance of spherical-cymbal transducer was investigated. Theoretical Von Mises stress analysis was carried out using finite element method. Effects of cavity geometry and material selection on limits pressure were evaluated. It shows that cavity depth, end-cap thickness and end-cap materials have strong effects on pressure tolerance of spherical-cymbal transducers. The comparison analysis indicates that the pressure tolerance of spherical-cymbal transducers with reference dimensions is higher than that of traditional cymbal transducers. |
