The Research On Wire Rope Quantitative Detection And Safety Evaluation

Wire rope is widely used in our daily life, its safe is directly related to life safety and normal production. Therfore, it is urgent to establish wire rope safety evaluation of scientific target system and weight system for state forecasting and estimation, to ensure the operation security and economization.Firstly, all kinds of wire rope damage types and characteristics are analyzed, localized fault and loss of metallic cross sectional area are two main quantitative detection parameters. It put emphasis on establish the model of the leakage magnetic signal and damage actual value based on genetic algorithm and the radial basis function neural network for localized fault quantitative detection. Its effectiveness is verified by instance analysis. Secondly, according to the localized fault quantitative detection results obtained by using nondestructive testing instrument, residual intensity and the safety coefficient are analysed to offer important reference for wire rope safety evaluation. A software for wire rope state evaluation based on wire rope safety regulation and scrapping standard is developed, and defect quantitative judgments residual intensity quantitative assessment、safety coefficient and life prediction are preliminary achieved.Finally,the research achievements and shortcomings are summarized. The basic idea of further research work is put forward to improve the accuracy of detection and safety assessment.
