The continuous push for lightweighting in the many industries to enhance fuel efficiency
requires a detailed understanding of existing structural components. This research presents a
comprehensive structural assessment of an accessory mount to establish a detailed baseline of its
mechanical performance. The primary objective was to characterize the component's response to
simulated operational loads. Using the finite element method (FEM) within the ANSYS software
platform, a static structural analysis was conducted. The model utilized a magnesium alloy, defined by its
main elastic properties and density of 1800 kg/m3. The analysis successfully mapped the distribution of
internal stresses, strains, and physical displacements. The results identified a maximum von Mises stress
of 237.2 MPa, which was found to be highly localized at the fillets of the mounting holes. Concurrently, a
separate analysis of displacement showed a maximum total deformation of 2.0683 mm, with this peak
deflection occurring in the component's unsupported central span. The equivalent elastic strain
distribution was found to be in direct correlation with the stress results. The study also highlighted that
significant regions of the component's main body are subjected to minimal stress levels. This work
concludes by providing a complete quantitative characterization of the accessory mount's structural
behavior, establishing a critical performance baseline for future design iterations.
