According　to　the　characteristics　of　the　wire　rope,　this　paper　introduces　some　methods　of　flaw　detection.　The　thesis　takes　flux　leakage　detection　as　core　and　develops　the　detection　method　which　is　effective　and　undamaged　to　study　and　analyze　the　wire　rope.　In　order　to　improve　the　accuracy　of　signal　detection　analysis　and　the　reliability　of　detection,　this　thesis　has　got　abundant　experimental　signals　of　broken　wire　to　denoise　and　decompose　the　signal　with　wavelet　analysis.It　extracted　the　fault　signal　characteristic　parameters　with　wavelet　reconstruction　to　judge　the　fault　type　for　building　fault　signal　sample　datebase.　The　thesis　eatablished　a　typical　wire　rope　fault　diagnosis　system.　©　(2012)　Trans　Tech　Publications,　Switzerland.
