Analyzing the influence of the core pre-structure on the dynamic response of a magnetorheological elastomer sandwich structure

Abstract Recently, vibration control has been useful in various engineering fields such as aerospace, adaptive dynamic absorbers, and infrastructure. Magnetorheological elastomer (MRE) is an interesting material for controlling suppressing undesirable vibrations through the application of a magnetic field. The present study aims at analyzing pre-structure magnetorheological viscoelastic core response MRE-sandwich structure. forced tests were performed under non-homogenous field to evaluate properties structure frequency bandwidth range 0–250 Hz. Experimental results show that proposed structures are capable eliminating unwanted resonances due induced intensity activated region, especially fundamental mode. Moreover, highlight oriented attenuation effect on low range. Additionally, external increased structural damping capability by approximately 200%. In addition, pre-structures MRE also used dissipate vibration. Consequently, they could potentially be applications stop operations structures.
