| 中文摘要: |
| 当Ｔｏｎｐｉｌｚ换能器组件中横截面面积之间相差较大时，应力、应变会有一定的突变，边界条件将不很连续，用四端网络方法设计会带来较大的误差．本文用有限元方法，设计并研制了一稀土Ｔｏｎｐｉｌｚ型换能器．实验测试表明，与四端网络设计法相比，有限元方法具有更好的设计精度。 |
| 英文摘要: |
| When large difference in the cross sectional areas occur between components of Tonpilz transducer, the stress or the strain will not be continuous at the junctions. The assumption of continuous boundary conditions will not hold in situations, like the designing by the use of the four terminal networks be continuously as well. In this paper, a rare earth giant magnetostrictive Tonpilz transducer is designed and manufactured by means of the finite element method. It is shown through experimental measurement that the design precision of the finite element method is better than that of the four-terminal networks design method. |
