Retrospective Analysis of Amusement Rides Accidents Based on Cognitive Reliability and Error Analysis Method

Abstract

Human factors are one of the important reasons for amusement rides accidents. Therefore, it is of great significance to establish a safety system of amusement rides centered on human safety. This research, as part of China's National Quality Infrastructure Project, is a sub-project of The Research on Full-lifecycle Testing, Monitoring and Integrity Evaluation Technology of Manned Rides. In this paper, Cognitive Reliability and Error Analysis Method (CREAM) is used to study the causes of accidents. Through statistics and analysis of the human error accidents of the amusement rides, the paper clarifies the human factors affecting the accidents, and establishes the basic path of the cause analysis of the amusement rides. On this basis, according to the framework of the CREAM retrospective analysis method, the human factor error modes of the amusement rides are analyzed, and the antecedents of the accident are identified. An antecedent analysis table for the human error modes was formed, and an Antecedent-Consequence Chain of amusement rides was constructed. In the end of this paper, a retrospective analysis of the cause of the accidents in the amusement rides in Xi'an, China was conducted. The research result of this paper constitutes one of the foundations of the safety evaluation of the entire life cycle of amusement rides.
