摘要

钢丝绳经常在恶劣的环境中使用,很容易损坏,内部可能会出现不同形状和大小的缺陷。因此,检测和分析内部缺陷尤为必要。传统的磁偶极子理论是无损检测中广泛使用的方法,但在准确计算内部缺陷时往往会遇到限制。本文介绍了磁偶极理论中的一种先进方法,即结合等效磁荷计算,从而开发出一种专门针对钢丝绳内部缺陷的磁通量泄漏(MFL)模型。这种增强型模型有助于分析由不同几何形状(包括矩形、梯形和三角形)的缺陷引起的 MFL 强度。理论结果已通过模拟和实验进行了验证,模拟误差保持在 3% 左右,实验误差低于 10%。这一验证强调了所提出的理论在检测钢丝绳内部缺陷方面的有效性,有可能加强钢丝绳使用过程中的安全措施。

Research on the Magnetic Leakage Field of Internal Defects in Steel Wire Ropes Based on the Magnetic Dipole Model
The steel wire ropes are often used in a harsh environment and are susceptible to damage, with varying shapes and sizes of defects that may occur within it. This leads to potential safety risks during usage; thus, the detection and analysis of internal defects are especially necessary. Traditional magnetic dipole theory, a widely employed approach in non-destructive testing, often encounters limitations in accurately calculating the internal defects. This article introduces an advanced method in the magnetic dipole theory by incorporating equivalent magnetic charge calculations, thus developing a magnetic flux leakage (MFL) model specifically for internal defects in wire ropes. This enhanced model facilitates the analysis of MFL intensity caused by the defects of diverse geometries, including rectangular, trapezoidal, and triangular shapes. The theoretical results have been validated through simulations and experiments, maintaining a simulation error of approximately 3% and an experimental error under 10%. This validation emphasizes the effectiveness of the proposed theory in detecting internal defects in wire ropes, potentially enhancing safety measures during their usage.
