摘要:
主要利用ANSYS有限元模拟软件，对受轴向拉力且有预制缺陷的50Mn钢丝绳单丝分别进行静力场计算和受环境磁场及自身剩磁场共同作用下的三维静磁场磁标量计算，并对两种物理场进行直接力-磁耦合分析，得到随着外荷载不断增加，试件缺陷处法向漏磁信号B(x)及其梯度值K的分布情况．结果表明，随着应力集中程度的不断增加，试件缺陷处的法向漏磁场信号B(x)出现过零点，其梯度值K出现极大值．最后，将试验结果与模拟结果进行对比，证明了模拟的可靠性．进一步证明了有缺陷钢丝绳的早期损伤与金属磁记忆信号之间的内在联系规律，该数值模拟方法可为钢丝绳拉伸磁记忆有限元分析提供参考．
Abstract:
The 50Mn monofilament steel wire rope with defects was axial tensions, which were respectively calculated in the static loading field and in the environmental magnetic field as well as the residual magnetic field itself 3D static magnetic field, the magnetic scalar calculation was finished by ANSYS finite element simulation software. The two physical field on magneto-mechanical coupling was analyzed directly, and along with the load increasing, getting the distribution of the normal magnetic flux leakage signals B(x) and its the value of the gradient K at the specimen defect. As a result, with the increase of the stress concentration level, the normal magnetic flux leakage signals have signal zero crossing and its the value of the gradient K has a maximum value. Finally, comparing with the test results and simulation results, it proves the reliability of the simulation. The relationship between the defective early damage of the steel wire rope and the metal magnetic memory signals were found by further research, which shows that the numerical simulation method can provide the reference for magnetic memory finite element coupling analyzed for steel wire rope tension loading.
