Abstract
In many industrial applications, laminated composite materials with their distinctive characteristics are preferred as the main structural components. Due to its substantial damping and stiffness attributes, Glass Fiber-Reinforced Composite material (GFRC) is one of the most used composite structures in the isolation area. GFRC materials’ dynamic properties are primarily influenced by three factors: stacking sequence, fiber orientation, and fiber volume fraction. In terms of design parameters for composite material, the objective of this study is to model and optimize the dynamic behavior of GFRC plates for modelling isolation and vibration control level. In addition, this work aims to study the impact of integrating a mechatronic control system with the GFRC isolation system to control transmitted vibration levels and enhance the machining process stability. To achieve these objectives, Response Surface Methodology (RSM) and Taguchi approach are two modelling and optimization techniques that are used to shrink the number of conducted analyses and generate a custom test array. The proposed test array was employed to accomplish this study for 10 layers of symmetrical glass/polyester composite plates with various lamina orientations of 0°, ±35°, ±45°, and 90°. The significant design parameters and the best combination levels have been determined. Based on RSM, mathematical modelling of the dynamic performance has been developed. For the fabricated GFRCs, Autodesk Helius Composite software 2022 package is used to calculate the orthotropic material properties and The dynamic properties ( natural frequencies and mode shapes) are investigated using Finite Element Analyses (FEA) by employing Solidworks simulation software 2022 package for numerical analyses. Experimental modal analysis is carried out using B&K data acquisition analyzer to verify the numerical results and obtain the dynamic characteristics (natural frequencies and damping ratios). The numerical and experimental results are presented and discussed to design and fabricate the optimum configuration of composite plate for isolation and vibration control nature. Finally, a mechatronic control system was coupled with the GFRC isolation system to control vibration transmitted to the machine foundation and enhance the machining process stability.
