英文摘要 | Dynamic characteristics analysis of sandwich orthotropic rectangular plate with magnetorheological (MR) elastomer is considered in this study. The orthotropic rectangular plate is covered a MR elastomer core treatment and a constraining layer to improve the vibrational behaviors of the system. Finite element method is utilized to derive the equations of motion for the orthotropic sandwich plate system. The effects of the natural frequencies and loss factors of sandwich orthotropic plate system are calculated and discussed. The rheological property of the MR material can be changed and controlled by applying various magnetic fields. Additionally, the modal dampings and the natural frequencies for the orthotropic sandwich plate are calculated for various magnetic fields. The effects of the strength ratio of the base rectangular plate on the natural frequencies and modal loss factors are also discussed. |
