英文摘要 | The dynamic stability control analysis problems of sandwich annular plate with an electrorheological (ER) fluid core and constraining layer are investigated. In this study, the annular plate system is covered an ER fluid core and a constraining layer. And, the discrete layer annular finite element and the harmonic balance method are used to obtain the instability regions of the sandwich annular plate system. It can be observed that the damping effects of the system can be controlled when different electric fields are applied on the sandwich structures and the ER fluid core is found to have a significant effect on the location of the boundaries of the instability regions. Additionally, variations of the instability regions of the sandwich annular plate with different applied electric fields and thickness of ER layer are studied and discussed in this paper. |
