The objective of this project is to analyze and optimize the bracket's weight by selecting a different material. Reducing the weight of the bracket not only helps decrease raw material costs but also improves overall efficiency, although the impact may be minimal. This study also aims to identify the factors that contribute to bracket failure and assess the effects of optimization through various analyses, including vibration analysis, deformation analysis, and Von Mises stress analysis. The project involves the design of an AC mounting bracket, which is created using modeling software and analyzed using ANSYS Software. The design of experiments (DOE) technique is employed to develop a glass fiber reinforced plastic (GFRP) bracket. The GFRP bracket is then subjected to analysis using ANSYS to evaluate its performance.
Fig.1.1:- Compressor Mounting Bracket Optimization is a fundamental aspect of problem-solving in a range of disciplines, including engineering and economics. The process of decision-making involves making choices among different options, and the goal is to make the optimal decision. The evaluation of these alternatives is typically determined by an objective function or performance index, which measures their quality. Optimization theory and methods are concerned with identifying the best possible alternative based on the given objective function.
The project reports a weight reduction of 66.67% achieved in the redesigned bracket. Additionally, the frequencies of the steel and composite brackets are to be checked. This refers to assessing the natural frequencies or resonant frequencies of the brackets to ensure they fall within acceptable ranges. It is crucial to avoid resonances that could lead to excessive vibration or failure. The project suggests that the GFRP bracket offers advantages over the steel bracket in terms of vibration. The vibration levels of the GFRP material are measured by connecting a probe to monitor acceleration and displacement in relation to the motor's RPM. Furthermore, the weight reduction achieved through the GFRP compressor mounting bracket leads to reduced noise compared to the steel bracket.
1.1 Composite Material 1.1.1 Polymer Matrix Composite Resins like epoxies and polyesters alone do not possess high mechanical properties, limiting their use in structural manufacturing. However, when combined with reinforcement in the form of fibers, the resulting composite exhibits enhanced tensile and compressive properties compared to the solid resin. These properties may not be immediately evident in the individual components.

Fibers in the composite primarily contribute to tensile strength along their length. When the fibers are integrated with the resin, the load applied to the composite is distributed across the resin, effectively spreading the load among the individual fibers. The combination of resin and
