【 摘 要 】

The article discusses the magnetic circuit of the developed magnetoelastic sensors of mechanical forces used in the systems of functional diagnostics of electric locomotives is investigated, taking into account the distribution of the magnetic resistance of coaxially arranged ring cores, the magnetic capacitance of the ring gap between them, the section of magnetizing and measuring windings. It is shown that the magnetic voltage along the sensor magnetic circuit is nonlinearly distributed and changes its sign at the magnetic neutral point, and the magnetic flux is non-constant and has a minimum value at the magnetic neutral point, and with an increase in the magnetic flux attenuation coefficient in the magnetic conductor magnetic flux along the length of the magnetic circuit increases.
