提出新型的磁通平衡检测原理,可有效提高损伤的检测灵敏度。在此基础上,设计了钢丝绳损伤动态探伤系统,详述了系统的总体结构和软件实现。应用表明:该系统具有便捷、快速、直观地检测和评价钢丝绳的使用状态,具有极高的重复性和准确性。可以应用于其他各类重要用途钢丝绳故障状况的在线实时监测。 Proposed a new type of magnetic flux balance detection principle, which can effectively improve the detection sensitivity of injury. On this basis, the dynamic inspection system of wire rope damage is designed, and the overall structure and software of the system are described in detail. The application shows that the system has the advantages of high speed repeatability and accuracy in detecting and evaluating the using state of the rope conveniently, rapidly and intuitively. It can be applied to online real-time monitoring of the fault condition of other kinds of important use wire ropes.
