| 中文摘要: |
| 文章中介绍了大尺寸超声振动体的研究进展。包括分析耦合振动的表观弹性法;用表观弹性法对短圆柱体、空心圆柱体和矩形六面体的振动进行分析;用开槽、开狭缝、附加弹性体和二次设计等方法对超声振动体的振动进行控制。对有关结果与用有限元方法进行计算的结果进行了比较,并作出了评价。 |
| 英文摘要: |
| An overview of the research on vibration of large sized ultrasonic vibrators is presented. Topics discussed in this paper include the apparent elasticity method, vibration analysis of short column, hollow cylinder and block-like resonator with the apparent elasticity method and vibration control methods such as slotting, fine slotting, additional wave-trapped horn and redesign. Comparisons and evaluations are provided based on FEM results. |
