A Damage Identification Method for Messenger Wire in Electrified Railway Based on Improved Synergetics
Authors: , ,
Abstract: Facing the problem of damage identification of messenger wire in the complex environment, a damage identification method for messenger wire in electrified railway based on improved Synergetics is put forward. Firstly, the method establishes a preliminary recognition mechanism, which includes the kinetic process of damage recognition, the development of cooperative identification model and the features extraction for messenger wire. Subsequently, this paper introduces the feedback identification mechanism combined by features evaluation and eigenvector reconstruction processes, which can be used to rise the correct rate of recognition. The experiment results showed that in the disturbance and noisy rich environments, the proposed method can identify different depths of cracks well, and the correct rate of recognition has risen to 100% when the feedback identification mechanism is introduced. This proposed approach not only demonstrates a strong ability to reject noise and disturbance, but also overcomes some shortcomings, such as the requirement of massive samples, being vulnerable to environments. Therefore, it will lay the foundation for the structure damage identification in the other more complex environments.
