Dynamic Behavior Analysis of the Sandwich Beam Structure with Magnetorheological Honeycomb Core under Different Magnetic Intensities: A Numerical Approach

Abstract

In this article a sandwich beam structure with honeycomb core filled of MRE (magnetorheological elastomer) with different ratios of Elastomer and iron particles is proposed. Modal response for structures with Nylon and Resin8000 honeycomb core filled with MRE and sandwiched between aluminum face sheets were analyzed and compared for two different ratios of MRE by placing magnets at free end and center of the structure. The force generated by magnets on the sandwich beam structure was calculated using ANSYS EDT and the modal response of the structure was then observed under generated magnetic force using ANSYS Workbench. The results showed that the resonance frequency of the structure decreased as the magnetic intensity was increased for all the cases specially for the first mode. Secondly structure with Nylon honeycomb core showed lower frequency drop and higher deformation than the structure with Resin8000 honeycomb core.

Dynamic Behavior of Sandwich Structures with Magnetorheological Elastomer: A Review

“…They concluded that the vibration amplitude of the sandwich panel reduced the magnetic field on the free end of structure was increased, and the downside shifted in natural frequencies [93], as shown in Figure 11. The numerical analysis of a sandwich beam with a hexagonal honeycomb of different materials and an MRE core was conducted by Sharif et al [94,95], and the down shift in natural frequency was observed for the first three modes for all the structures when the magnetic field was increased.…”

Damping and Stiffness Analysis of Sandwich Beam with 3D-Printed Honeycomb Core Filled with Magnetorheological Elastomer (MRE): An Experimental Approach

“…Furthermore, scholarly research has been conducted on the subject of material empirical modeling, as evidenced by studies [ 29 , 30 , 31 , 32 , 33 ], Additionally, investigations have been carried out on material development and property testing [ 34 , 35 , 36 ], innovative device design and characterization [ 37 , 38 ], performance evaluation [ 39 , 40 , 41 , 42 ], and sandwich beams [ 43 , 44 ]. Several studies have also investigated the dynamic analysis of sandwich constructions made with magnetorheological gel (MRG) MREs [ 45 , 46 , 47 , 48 ]. The sandwich construction exhibits a notable ratio of stiffness to weight, which enables the effective integration and optimization of diverse materials for both the surface and core layers.…”
