Description
(54) УСТРОЙСТВО ДЛЯ НАЛАДКИ ПРИБОРОВ БЕСКОНТАКТНОГО ИЗМЕРЕНИЯ КОЛЕБАНИЙ ЛОПАТОК ТУРБОМАШИНЫ(54) DEVICE FOR ADJUSTING INSTRUMENTS OF CONTACTLESS MEASUREMENT OF VIBRATIONS OF TURBO MOBILE BLADES
Временной интервал между импульсами от периферийных датчиков определ ют следующим образомThe time interval between pulses from peripheral sensors is determined as follows.
, Sin ( 16, ) A.jsirt ( + dp, Sin (16,) A.jsirt (+ dp
где At - врем , завис щее от начального расположени датчиков;where At is the time dependent on the initial position of the sensors;
и окружна скорость штьц ьков; - амплитуда, частота к фазовый угол колебаний первого датчика;and the circumferential speed of the bars; - amplitude, frequency k phase angle of the first sensor;
V - амплитуда, частота и фазовый угол колебаний второго датчика.V is the amplitude, frequency and phase angle of oscillations of the second sensor.
Подбира соответствующим образом амплитуды; частоты и фазы колебаний датчиков и измен часто- . ту вращени дисков, можно получить имитацию колебаний лопаток, подчин ющуюс любьгм законам. Таким образом можно имитировать автоколебани лопаток, колебани от вращающегос срыва, срывание и резонансные колебани лопаток. Скважность импульсов можно измен ть, уменьша или увеличива число щтырьков на основном даске 3.Matching amplitudes accordingly; frequencies and phases of oscillations of sensors and changes in frequency. By rotating the discs, it is possible to obtain an imitation of the oscillations of the blades, subject to any laws. In this way, auto-oscillations of the blades, oscillations from a rotating stall, stalling and resonant oscillations of the blades can be simulated. The pulse duty cycle can be changed by decreasing or increasing the number of pins on the main box 3.
