Magnetic flux leakage (MFL) method is an important way to detect the fault of steel wire ropes and the sensor for the collection of MFL plays a vital role in the damage detection. Among varied sensors based on MFL method, the magnetic concentrating sensor shows a lot of advantages in the detection of wire ropes. The use of the magnetic concentrator can assist the magnetic sensitive component to detect the MFL and reduce the number of the Hall components. The lift-off of the magnetic concentrating sensor can also be set to a feasible value which is easier to be ensured in the practical application. Although many researches on the magnetic concentrating sensor have been carried out, few of them have a comprehensive and thorough investigation, which should include the simulation analysis, the prototype design, the broken wire experiment and the comparison with other commonly used sensors. In this paper, a magnetic concentrating sensor is developed and compared with a Hall array sen...

用于钢丝绳损伤检测的磁选传感器的综合研究

漏磁法是检测钢丝绳故障的重要方法，而漏磁传感器在损伤检测中起着至关重要的作用。在基于MFL方法的各种传感器中，磁集中传感器在检测钢丝绳方面显示出许多优势。磁性集中器的使用可以帮助磁性敏感组件检测MFL并减少霍尔组件的数量。磁集中传感器的提离也可以设置为在实际应用中更容易确保的可行值。尽管已经进行了许多有关磁集中传感器的研究，但很少有涉及到全面而透彻的研究，其中应包括仿真分析，原型设计，断线实验以及与其他常用传感器的比较。本文开发了一种磁集中传感器，并将其与霍尔阵列传感器进行比较。
