針對礦用在役提升鋼絲繩由于擺振等原因?qū)е碌拇呕痪鶆騿栴},提出了一種徑向永磁環(huán)組合勵磁結(jié)構。首先,根據(jù)畢奧–薩伐爾定律對永磁環(huán)磁場分布進行了理論建模。然后,從理論上分析了影響永磁環(huán)的磁場分布的關鍵參數(shù)及對其磁場分布的影響規(guī)律,為勵磁結(jié)構參數(shù)設定奠定了理論基礎。最后,運用優(yōu)化后的軸向永磁環(huán)組合和徑向永磁環(huán)組合勵磁結(jié)構對鋼絲繩正常與擺振運行下的均勻磁化效果進行了仿真對比分析,結(jié)果表明:本文提出的徑向永磁環(huán)組合勵磁結(jié)構比同體積軸向永磁環(huán)組合的勵磁結(jié)構磁化效果較好,前者更容易安裝更換傳感器和聚磁器,簡化了磁化器,且擺振擾動對鋼絲繩的均勻磁化影響較小。本研究為礦用在役提升鋼絲繩損傷定量評價奠定了基礎,有效預防礦用提升鋼絲繩斷裂事故的發(fā)生。Aiming at the problem of uniform magnetization of steel wire rope in service due to vibration,a radial permanent magnetic ring combined excitation structure was proposed.Firstly,according to Biot Savart law,the magnetic field distribution of permanent magnet ring was modeled.Then,the key parameters affecting the magnetic field distribution of the excitation structure and the influence law on the magnetic field distribution were analyzed theoretically,which provided a theoretical foundation for setting the parameters of the excitation structure.Finally,the uniform magnetization effect of the steel wire rope under normal and vibration operation was simulated and analyzed by using the optimized axial permanent magnet ring combination and radial permanent magnet ring combination excitation structures.The results showed that the magnetization effect of the radial permanent magnet ring combination excitation structure proposed is better than that of the axial permanent magnet ring combination excitation structure with the same volume,and it is easier to install and replace the sensor and magnetic concentrator.The magnetizer is simplified,and the influence of vibration disturbance on the uniform magnetization of wire rope is small.This study lays a good foundation for the quantitative evaluation of mine hoisting wire rope damage in service,and it is of great significance to effectively prevent the occurrence of lifting wire rope fracture accidents.
