This paper describes an experimental study of lifting cable fault diagnostic based on instantaneous angular speed (IAS) technique. During the study load tests on a selection of damaged cables, it is shown that IAS increases significantly after the damage is inflicted. The relationship between IAS signal characteristics and strand defects is investigated and it is found that the most influent parameters over IAS are speed, load and defects size. The pattern of IAS signals during a detection fault test is studied and a suggestion is made for a filtering technique to improve the recognition of imminent failure. Finally, an evaluation of the common statistical indicators was implemented. The study gave satisfactory results and shown that IAS measurement is a promising tool for the health monitoring of low speed cables.

本文介绍了基于瞬时角速度（IAS）技术的提升电缆故障诊断的实验研究。在对选定损坏的电缆进行的研究负载测试期间，表明在造成损坏之后，IAS会显着增加。研究了IAS信号特性与线缺陷之间的关系，发现在IAS上影响最大的参数是速度，负载和缺陷尺寸。研究了IAS信号在检测故障测试过程中的模式，并提出了一种滤波技术以提高对即将发生的故障的识别的建议。最后，对共同的统计指标进行了评估。这项研究给出了令人满意的结果，并表明，IAS测量是用于低速电缆健康状况监测的有前途的工具。
