Преобразователи параметров динамических перемещений лопаток турбоагрегатов, основанные на нелинейной аппроксимации первичных сигналов

Abstract

В статье предложена новая реализация дискретно-фазового метода, позволяющая определить параметры колебаний лопаток турбомашин при помощи анализа искажений формы сигнала первичного преобразователя. Колебание лопаток приводит к искажению формы сигнала первичного преобразователя, анализ искаженного сигнала методами нелинейной аппроксимации позволяет определить параметры колебаний лопатки.

New method for the determination of blades oscillation parameters is proposed. The approach is based on the analysis of primary transducers signals distortions using nonlinear approximation techniques. Blades oscillations lead to distortions of primary transducer output signal, non-linear approximation techniques allow to determine blade oscillation parameters.
