Parametric Investigation of Mechanical Aspect for TV Wall Mount Bracket via Finite Element Analysis

Abstract

Nowadays, most flat screen television (TV) come with a feature that allows users to mount the TV and it takes some effort on the user's part to attach the mount to the wall and the TV to the mount. Various TV wall mount designs available on the market with different dimensions, thicknesses, and materials may cause mechanical problems. This study aims to analyze the effect of the design parameters on the wall mounting bracket and evaluate the best design parameters for minimal mechanical defects. The validated 3D model is simulated using SolidWorks software. Different wall mount lengths, widths, thicknesses, and TV wall mount bracket designs are selected as factors in this study. Meanwhile, stress, displacement, and strain are selected as responses in this study. Statistical regression analysis analyzes the correlations between design parameters and mechanical defects. The analysis shows that 6 mm thickness, 430 mm length, and 160 mm width have the lowest stress, strain, and displacement. Design 3 is the best wall plate design to minimize stress and strain. To conclude, the results of this study could make the TV wall mount bracket a universal mounting for various weights of TVs.
