Abstract

Способ вибрационной диагностики двигателя путем измерения частоты вращения ротора и виброускорений корпуса и ротора двигателя, определения амплитуды, частоты и типа колебаний следящим спектральным анализом с автоматической настройкой на измеряемую гармоническую составляющую вибраций по сигналам датчика частоты вращения ротора, отличающийся тем, что, с целью повышения точности, амплитуды вибраций определяют непрерывно при изменении частоты вращения ротора от минимальной до максимальной, находят зону резонансных колебаний ротора и при наличии в этой зоне двух максимумов амплитуды, соответствующих одному типу колебаний ротора, для каждого из этих максимумов определяют частоты колебаний ротора и по разности этих двух частот определяют степень неоднородности динамических свойств ротора и нарушения его конструктивно-поворотной симметрии.The method of vibration diagnostics of the engine by measuring the rotor speed and vibration accelerations of the body and rotor of the engine, determining the amplitude, frequency and type of oscillations by tracking spectral analysis with automatic tuning to the measured harmonic component of vibrations by the signals of the rotor speed sensor, characterized in that , the vibration amplitudes are determined continuously as the rotor speed changes from minimum to maximum, find a zone of resonant oscillations of the rotor and When present in this zone of the two amplitude maxima corresponding to one type of rotor vibrations, for each of these peaks determines the oscillation frequency of the rotor and the difference between these two frequencies determine the degree of heterogeneity of the dynamic properties of the rotor and its structurally-breach of rotational symmetry.
