Abstract

Способ снижения вибрации в устройстве, которое имеет по меньшей мере один ротор (101 j) и комплект неподвижных источников (102 j; 14) возмущений, способных вызвать возмущение в потоке (11) текучей среды, что приводят к вибрации ротора. Способ по изобретению включает этап неравномерного углового распределения неподвижных источников возмущений таким образом, чтобы снизить амплитуду воспринимаемого ротором возбуждения, и этап верификации того, что достигнуто снижение максимальной амплитуды реакции ротора на возбуждение. Верификация предусматривает выполнение таких этапов: определяют первый сигнал, для которого преобразования Фурье соответствует частотному спектру возбуждения для случая, когда неподвижные источники возмущений распределены соответственно предварительно определенному угловому распределению, модифицируют первый сигнал во второй сигнал, адаптированный к выбранному угловому распределению неподвижных источников возмущений, определяют частотный спектр возбуждения, рассчитывая преобразование Фурье второго сигнала, и базируясь на частотном спектре возбуждения, рассчитывают реакцию ротора на возбуждение.
