| 中文摘要: |
| 以V型双动圈电动式激振器为例,建立了激振器可动系统的有限元模型,并进行了模态分析,发现双动圈激振器频响曲线上出现的较大谷峰是由于可动系统在轴向的对称结构造成的,为进一步的结构优化设计提供了依据. |
| 英文摘要: |
| Movable system is the key component of an electrodynamic shaker whose dynamic characteristics determine the shaker’s frequency response.This paper is based on V-model dual-moving-coil electrodynamic shaker.The finite element model of the shaker movable system is established.The subsequent model analysis reveals that the steep troughs and peaks existing in the frequency curve result from the axial symmetric structure of the movable system.The findings can provide basis for further structural optimized design. |
