“…Several contact sensors were used to measure the magnetostriction of ferromagnetic materials. In order to overcome the disadvantage and limitations of the contact sensors, a contactless measuring system by means of a laser displacement sensor is developed and used in practical vibration measurement [32,33,34,35,36,37,38].…”

As an intrinsic property, elasticity of soft material is affected significantly by the externally applied alternating magnetic field. Magnetostrictive properties of the grain-oriented (GO) silicon steel under DC-biased and multisinusoidal magnetizations are measured by using a laser-based measuring system. Magnetostriction curves of the GO silicon steel sheet under different magnetizations are obtained and the influence of frequency and DC bias on the magnetostrictive property is observed and analyzed based on the measured data. In addition, the spectrum of magnetostriction under harmonic magnetization is obtained, and the acoustic noise level of the GO silicon steel sheet represented by the A-weighted decibel value caused by magnetostriction is measured under DC-biased and multisinusoidal magnetizations. The measurement results are applied to the simulation of the three-limb laminated core model, and the effects of DC bias and harmonics on magnetic flux density and displacement are analyzed.

“…With the improvement of manufacturing technology, the electromagnetic force caused by magnetic flux leakage between the core laminations and joints is far less than the magnetostrictive force, so the vibration induced by electromagnetic force can be ignored compared with the vibration induced by magnetostrictive effect [27]. The magnetostriction of the ultrathin silicon steel sheet is nonlinear with the magnetic field [28]. The anisotropy, applied stress, and temperature will have a great influence on the magnetostriction of silicon steel sheet [29][30][31].…”

The cores of anode saturated reactor (ASR) are the main vibration source of the HVDC converter valve system. The ASR is excited with an impulse voltage, which contains many harmonic components, and the magnetostriction of cores is usually the main reason of the ASR vibration. Therefore it is significant to study the influence of the harmonic on the vibration of core of ASR. In this paper, the magneto-mechanical coupling model is established based on the magnetostriction theory and the expression of vibration acceleration in the presence of third harmonic is derived. The vibration test platform is built to test the core's vibration acceleration. The magnetic and magnetostrictive properties of silicon steel sheet under different working conditions are measured. The three-dimensional simulation model of the core is established, and the vibration acceleration under different magnetic flux density is calculated. The comparison of the experiment and simulation results shows the rationality of the magneto-mechanical coupling model. The influence of third harmonic magnetic flux density on vibration is studied by changing the phase of the third harmonic magnetic flux density and the ratio of the third harmonic magnetic flux density to the fundamental magnetic flux density. Both the calculated and measured results show that the third harmonic magnetic flux density affects the vibration acceleration according to the double-frequency components of the third harmonic, as well the sum-frequency and difference-frequency components of the third harmonic and fundamental frequency.

“…On the other hand, some researchers adopt magnetostrictive elongation data to calculate the corresponding magnetostrictive forces according to the stress‐strain constitutive relations, and then the vibration displacement of the core can be obtained [8–10]. The magnetostriction of grain oriented silicon steel sheet has a complex non‐linear relationship with the magnetic field [11], the anisotropy of silicon steel [12], the pressed force, and annealing temperature have effects on the properties of magnetisation and magnetostriction of silicon steel sheet [13, 14]. Therefore, establishing accurately the mathematical model of magnetostriction is significant for the study on vibration and noise of saturable reactor.…”
