摘要: The complex shear modulus of an electrorheological (ER) adaptive sandwich beam is optimally estimated to model the system for vibration control. In composition a three layered beam, ER fluid layer embedded between two constraining layers. Using finite element (FE) method, governing equations composite viscoelastic are derived. developed compared with results found in literature. addition, fabricated ASTM E756 standard employed estimate different electric fields. An optimization procedure conducted based on particle swarm (PSO). this process, rough estimation extracted by modified correlate FE and experimental tests. updated mapped into appropriate form that can be used control objectives. Finally, semi-active sliding mode utilized atte...
