초록
Aerial work platforms are employed to enable efficient operations at elevated positions and confined spaces such as utility poles at various construction and civil engineering sites. As these platforms are mostly operated at positions higher than 10 m, it is essential to verify the structural stability for both the vehicle and the boom. This study investigates structural and mechanical characteristics of an aerial work platform boom under varying wind speeds through numerical analysis. The results indicate that increasing air flow leads to non-uniform pressure distributions around the boom surfaces with external load up to 172.9 Pa at joint part of high structural evaluation. Especially stress concentration was found at the joint between the 3rd and 4th booms, These findings demonstrate that aerodynamic loads induced by increasing wind speed contribute to boom deformation and stress distributions, and they provide a fundamental reference for stability verification with design optimization of the aerial work platforms.
