The safety evaluation of the steel gate is crucial to the scientific management the device.In consid-eration of the limitations of traditional single evaluation methods of the existing arc steel gate,the installa-tion quality,opening and closing force,corrosion degree and other safety evaluation indexes are considered comprehensively.Aimed at the characteristics of uncertainty and fuzziness in certain evaluation indicators compared with the traditional safety evaluation,the timing weighting algorithm was introduced to empha-size the change of each index of steel gate under the passage of time,and the combined weight was obtained by using the three-scale method and the entropy method.Finally,the combination of weights,and the com-bination of dynamic and static subjective and objective weights was realized,and a scientific and reliable cloud evaluation model of the safety state of the arc steel gate based on dynamic weighting was construc-ted.The engineering application results show that the established evaluation model can not only quantita-tively and intuitively reflect the safety evaluation level of the arc steel gate,but also reflect the time evolu-tion law of the evaluation level,making the evaluation results more in line with the actual situation and better reflecting the operating status of the steel gate.
