摘要: 振动台在高频振动过程中难免会产生空间的小角度运动,这种角运动在振动试验中是非预期的,应尽量减小。利用激光干涉原理,运用双频激光干涉仪及角度测量组件测量了振动台振动频率达2 000Hz时方位、俯仰、横滚三个方向的实时角度、角速率。通过对测量数据的分析可知环境的振动对测量准确度影响较大,为进一步完善该测试方法指明了研究方向。

Abstract: When vibration table vibrates in high frequency, dynamic angle error is induced. This dynamic angle is not anticipated, it is considered a kind of error of the vibration. A dual-frequency laser interferometer is used to measure the dynamic yaw angle、 pitch angle and roll angle respectively when vibration table vibrates in 2 000Hz. In this dynamic angle measurement method laser interference theory is used. We find the vibration of surroundings influences the result greatly by analyzing the test result. A study direction is found to prefect the dynamic angle measurement method.
