Strength Analysis of the Ferris Wheel

Abstract

This thesis investigates the structural integrity of a Ferris wheel through static structural analysis using the finite element method (FEM), assessing its strength in accordance with EN 1991-1-4 and ČSN EN 13814 standards. The analysis considers multiple loading conditions—including wind forces, self-weight, and passenger loads—simulated in ANSYS Mechanical. The results indicate that stress concentrations at critical locations, particularly the cabin hang bars, exceed the allowable steel yield strength which is 355Mpa with maximum stresses surpassing this limit. Such findings suggest a potential risk of material failure under expected operating conditions. The likely causes include the quality of the material used and the insufficient cross-sectional design of the hang bars, which may not adequately resist the applied loads. To address this, the thesis proposes optimization strategies such as redesigning the cross-section of the hang bars and utilizing higher-strength materials to mitigate stress concentrations and enhance the structure’s safety and durability. Although the current design does not fully meet strength requirements, the study offers valuable insights into the structural behaviour of Ferris wheels and presents recommendations for improving design efficiency while ensuring regulatory compliance.
