| 中文摘要: |
| 为更经济地制造出质量更高的Spherical-cymbal换能器端帽，在其成形中用自由液压胀形工艺取代传统的冲压工艺，并对其自由胀形中的回弹问题进行了重点研究。采用ANSYS/LS-DYNA软件对端帽的自由胀形回弹量进行了预测，并根据约束条件及有限元模拟结果提出了回弹控制措施。实验结果验证了采用有限元数值模拟进行Spherical-cymbal换能器端帽自由胀形回弹预测与控制的可行性。 |
| 英文摘要: |
| In order to manufacture spherical-cymbal transducer's end-caps with higher quality and lower costs, free hydro-bulging technology is used to substitute the traditional stamping technology, and the emphases are laid on the study of the spring-back of end-caps in free hydro-bulging. ANSYS/LS-DYNA software is adopted to forecast the spring-back of end-caps in free hydro-bulging. The controlling method is brought forward based on restrictions and the FEM simulation results. Experiment results prove that it's feasible to forecast and control the spring-back of end-caps by FEM numerical simulation. |
