Many new methods are produced through research of detection methods for objective constructs of wheel - sets : multi - kind of waves , multi - frequency , multi - angle and combined probe etc . . exploit smart analysis software which estimates size , position and remanent life of default and make relevant results more distinctly display in three - dimensional view 针对我国铁路轮对的具体结构，对探伤方法进行了研究，提出用多种波形，多频率，多角度、组合探头进行探伤的新方法，有效解决了漏探和错探问题，并可大幅度提高探伤速度。
