摘　　要：针对振动测量系统薄弱环节,从传感器、测量电缆两方面着手,分析了导致传感器灵敏度变化的原因。建立了测量电缆数学模型,提出了可靠性检测相关方法。试车验证了该方法的有效性。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 reliability checkout was proposed. The effectiveness of the vibration measurement system was verified in the rocket engine tests.
