【摘要】 钢丝绳作为提升、运输及承载设备中的关键部件被广泛应用于许多工程领域，其使用安全性至关重要。本研究针对钢丝绳实时在线无损检测问题，在全面分析和论述国内外钢丝绳状态检测技术研究现状的基础上，结合钢丝绳的电磁检测原理，研究了检测系统装置的搭建、钢丝绳缺陷信号的特征分析及检测软件的开发。本论文主要研究内容如下：1．建立了钢丝绳无损检测装置的硬件平台，实现对钢丝绳的检测信号的提取。2．利用MATLAB软件对提取的钢丝绳检测信号进行分析处理，以得到故障处的特征。3．分析故障处的数据以得到量化故障大小的方法。4．利用Visual C++开发了钢丝绳无损检测系统软件。本论文做了大量的测试与试验工作。由试验结果可以看到信号分析结果与钢丝绳故障状况基本相符，表明所开发的检测系统具有较好的实用价值，可以实现钢丝绳的无损检测。最后，总结了本文的研究工作，并就进一步的研究工作提出了一些设想。更多还原

【Abstract】 As a key part of hoist , transportation and bearing equipment, the steel rope is widely used in a lot of engineering fields, the security is one of the most important problems during its use. This research is put forward by the need of real-time on-line detection of steel rope. On the base of analyzing and discussing the domestic and foreign research in steel rope detection and the principle of electromagnetic detection, this paper sets up the detection system and develops the software for detecting the faults of the steel rope.The main contents of the paper are as following:1. A hardware platform has been established for the detection of steel rope ,which can pick-up the detection signal.2. Software MATLAB is used for the analysis of the detection signal, and the characteristics of steel rope faults are found.3. The data of the faults is analyzed, and the method for getting the amount of the faults is presented.4. A software for steel rope fault detection is developed by using Visual C++.A lot of experiments are done to test the system performance. Experiments prove that the result of signal analysis accords with the fact basically, which shows the system developed by this paper can be used to steel rope non—destructive testing, and it has a higher value in the reality of engineering.Finally, research work is summarized, expectation and assumption are put forward for further research.更多还原
