Analysis of Interface Characteristics of Tension Clamp Metal Structure under Edge Analysis
Tension clamp is an important accessory on overhead transmission line,but its grip strength decreases and loosens in the process of application,which brings some risks to the safe operation of transmission line.In order to fully grasp the application of tension clamp,a simulation analysis method of metal structure interface characteristics of tension clamp based on image edge feature extraction is proposed.Using this method,the sensor array structure of ten-sion clamp was designed,the boundary voltage of tension clamp was obtained,and the sensitivity matrix was construc-ted by using the boundary voltage;The interface image of the metal structure of the tension clamp was obtained after repeated projection processing of the sensitivity matrix;Then,the edge feature points of the metal structure interface of the tension clamp were obtained by using the edge feature vector reconstruction method;Based on the edge feature points,the three-dimensional model of the metal structure of the tension clamp was constructed by using MATLAB simulation software,and the interface characteristics of the metal structure were simulated.The simulation results show that this method has strong ability to extract the edge features of tension clamp metal structure,and can effectively simulate the stress characteristics of tension clamp metal structure interface.
