Abstract:
The causes of sensibility change of vibration sensors are analyzed in this paper in the aspects of sensors and measuring cables, which are the possible weak links of vibration measurement system. The mathematical model of measuring cables was established. The method relative to the re- liability checkout was proposed. The effectiveness of the vibration measurement system was verified in the rocket engine tests.
