Research on Quantitative Model of Risk Assessment for Amusement Rides
According to the features of amusement rides and the definition,the quantitative model of risk assessment for amusement rides was build based on hazard probability and hazardous consequence calculated with economical loss.According to the structure features that the amusement rides are composed with mechanical,electric control,hydraulic and other systems,the failure probability of electric control system was calculated with unit failure probability and simplified bathtub curve; and the failure probability of mechanical system is calculated according to the fatigue damage accumulation theory.The hazard probability is modified by comprehensive correction factor to consider the influence on the risk performance of amusement rides caused by the safety measures,redundancy units,strengthening process and management methods.The loss rate,direct economic loss and indirect economic loss are used to calculate the quantitative hazardous consequence.The steps of risk assessment based on the quantitative model were introduced.
