摘 要钢丝绳广泛应用于矿山、交通运输、旅游等国民经济各主要行业，发挥着极为关键的作用。钢丝绳作为工程承载的关键构件，在使用过程中极易发生磨 损、锈蚀、疲劳、断丝等各种形式的机械损伤，导致其安全承载能力下降，造成安全隐患。钢丝绳安全检测的原理、方法和技术的研究是非常重要的课题，具有重大的社会经济意义。因此，钢丝绳损伤检测已被世界各国高度重视，成为世界性的，既有理论意义又有实用价值的重要研究课题。对钢丝绳进行饱和励磁是能够准确检测到钢丝绳损伤信号的前提。本文基于磁路和磁场理论，建立了钢丝绳损伤的磁路计算模型，对影响励磁器性能的各种 因素进行了分析，设计制作了永磁式周向多回路励磁器。在此基础上，采用了高 性能的集成单感应线圈对钢丝绳损伤漏磁场进行检测，设计出了信号预处理电 路，提出了基于感应线圈钢丝绳损伤检测方法，在此基础上，提出以 AT89C52 单片机为微处理器的钢丝绳断丝信号特征量数据采集系统以及基于虚拟仪器技术对钢丝绳的损伤信号进行数据的定量识别与分析显示。关键词：钢丝绳；断丝；励磁器；感应线圈；单片机ABSTRACTThe steel wire rope is widely used in mining, transportation, tourism and other major industries of the national economy, playing an extremely critical role. As the key component of engineering bearing, the wire rope is very easy to break, rust, fatigue, broken wire and other forms of mechanical damage in the process of use, resulting in a decrease in its safety carrying capacity, resulting in safety hazards. The study of the principle, method and technology of safety detection of wire rope is a very important subject and has great social and economic significance. Therefore, the detection of wire rope damage has been attached great importance to the world, both theoretical significance and practical value of important research topics. Saturating excitation of wire rope is a prerequisite for accuratedetection of wire rope damage signal. Based on the theory of magnetic circuit and magnetic field, this paper establishes ...
