Risk Assessment Research For The Large-type Slipped Amusement Rides Based On The Matter-element Model

With the improvement of China's comprehensive national strength,the quality of national life has been greatly improved,and the pursuit of spiritual culture has become a mainstream trend.The large-type slipped amusement rides have been popular in recent years as an exciting and interesting amusement mode.The complex structure of such amusement rides makes them run at higher risk due to ill management,improper operation and poor safety awareness of personnel.Therefore,it is very important to propose an accurate and efficient method to evaluate its risk.However,through the study of literature,it is found that the previous researches on the large-type slipped amusement rides mostly used some traditional evaluation methods,which have the disadvantages of large subjective factors and large errors of sample learning,thus the evaluation results are distorted to a certain extent.In view of this,this paper started from the current situation of the large-type slipped amusement rides research and combined with characteristics of it,established the risk assessment model for large-type slipped amusement rides on the basis of the matter-element extension theory and entropy-weight theory.The evaluation results can not only determine the risk level of the large-type slipped amusement rides,but also realize the classification and evaluation of each index,so as to provide an effective basis for the safe operation and management of the the large-type slipped amusement rides.The main research contents and achievements of this paper are as follows:1.The paper summarized the development history and present situation of risk assessment methods for the the large-type slipped amusement rides at home and abroad,and discussed the necessity and significance of risk assessment for the the large-type slipped amusement rides.2.Considering the Systematization,comprehensiveness and complexity of risk assessment risk of the large-type slipped amusement rides,This paper based on the three elements of "Equipment-Human-Management",at the same time,combined with relevant national standards and the study of the literature to select 11 important evaluation indexes to evaluate the risk of the large-type slipped amusement rides.Thus the establishment of risk assessment index system for the large-type slipped amusement rides was completed.3.By studying the principle of matter-element extension theory and information entropy theory,and combining the characteristics of risk assessment for the large-type slipped amusement rides,this article constructed the risk assessment model for large-type slipped amusement rides.4.The paper applied the model to a roller coaster in an amusement park in Xi'an,the results of the assessment are basically consistent with the actual situation,and this shows that the model is effective in the risk assessment for the large-type slipped amusement rides.Through analysis of the risk assessment results,the paper put forward the countermeasures to reduce the risk of the large-type slipped amusement rides,and provided an effective basis for the daily safety management of its operating units.
