Abstract

The invention relates to a gate safety evaluation method, which is characterized by comprising the following steps: (1) analyzing the vibration test data of the hydraulic gate under different opening degrees and different speeds, and establishing a gate standard based on inverse distance weighting Vibration model; (2) Substitute the parameter data of the gate in the current operating condition under the test state into the trained standard vibration model of the gate, calculate the safety standard value of the gate vibration under the current operating condition, and compare the safety standard value with the current operating condition. The measured value of the condition is input into the gate vibration safety evaluation model, and the safety evaluation state of the gate is obtained. Based on the comprehensive description of the change process of the gate vibration, the invention can detect the possible abnormality in the gate operation process in advance, has good practicability, and has fast calculation speed and high calculation accuracy, and can be widely used in The security assessment area of ​​the gate.

Description

technical field [0001] The invention relates to a gate safety evaluation method, in particular to a gate safety evaluation method based on an inverse distance weighting model, belonging to the field of gate safety evaluation. Background technique [0002] Arc-shaped steel gates have become the most widely used in hydraulic structures due to their advantages of no door slot, small opening and closing force, reliable operation, good discharge conditions, and can meet the needs of various types of discharge channels. door type. [0003] The arc gate may vibrate during the opening and closing process or when it is partially opened. Moreover, due to gate design, installation, equipment quality problems, and structural static damage such as gate aging and corrosion, strong vibrations will occur when the gate is running. The strong vibration of the gate will cause fatigue, deformation, weld cracking of metal components of the gate, loosening of fasteners, damage of water seal and...
