摘要
提出了基于光纤陀螺技术的三轴振动转角测试方法,根据三轴试验需求组建了光纤陀螺转角测试系统。通过三轴振动试验应用该系统对振动台台面的转角位移进行了实测,对振动台面的实时角速度信号进行频域分析和处理。结果表明:基于光纤陀螺技术的三轴振动转角测试系统方案的可行性与正确性。
The method of rotation angle testing in three-axis vibration based on fiber optic gyroscope technique is proposed, and the theory of measurement is introduced as well. According to the measurement precision requirement, the angle testing system of FOG is designed by analyzing the environment of three-axis vibration. It is applied in experimental investigation of rotation angle in three-axis vibration with the testing system and the real- time angular rate signal is processed by frequency analysis and process. The results of practical application show the system scheme of angle testing method by means of FOG technique is feasible and correct.
