In view of the multi-factor influence of stress, deflection, vibration, corrosion and other factors involved in the state assessment of hydraulic steel gates, established a gate health assessment system including the target layer, criterion layer and indicator layer. A hydraulic health assessment model combining fuzzy analytic hierarchy process and improved radar chart method is proposed. In this method, the fuzzy analytic hierarchy process is used to determine the weight of each index, and then the improved radar chart method is used to evaluate the criterion layer and the target layer respectively, and the gate evaluation level is standardized and drawn into the radar chart. An example of comprehensive evaluation of a radial gate is given, which visually expresses the various factors that affect the gate. While giving the health evaluation result of the gate state, it fully reflects the actual state of all aspects of the gate.
Key words: Hydraulic gate / health assessment / fuzzy analytic hierarchy process / radar chart / comprehensive evaluation
