Abstract

The truss is a key part of a Ferris wheel system and affects the safety of the entire Ferris wheel system directly. This paper proposes an analytical method based on failure modes, effects, and criticality analysis (FMECA) and a fuzzy evaluation method for evaluating the risk level of the trusses of the Ferris wheel system; the analytical method includes qualitatively analyzing the operation, failure modes, failure cause, failure rate, and severity through FMECA and quantitatively assessing the safety by using the fuzzy evaluation method. A case study is presented to demonstrate the effectiveness, reliability, and practicability of the analytical method in assessing the risk level of the Ferris wheel trusses. The results show that the highest risk of the failure mode is truss fracture and that the truss itself has a lower level of risk. The results coincided with the real test.
