空间高微重力主动隔振系统加速度测量研究

为实现空间高微重力主动隔振系统的主动隔振性能,需要精确测量平台的振动。首先介绍采用线加速度计测量刚体线加速度和角加速度的动力学原理,给出加速度计配置时要满足的条件,然后提出两种六加速度计配置方式并给出加速度解算公式,着重分析了两种配置方式下加速度计的测量误差和安装误差对加速度解算精度的影响,给出了相应的误差模型和分析结论,这为加速度测量系统设计提供了依据。

Study on acceleration measurement in space high quality microgravity active vibration isolation system

In order to realize the excellent vibration isolation performance of Space High Quality Microgravity Active Vibration Isolation System(SHQMAVIS)，it's necessary to measure the vibration of space science ex-periment accurately. In this paper, the method of measurement of angular and linear accelerations using linear accelerometers is introduced. The press is put on the proposal of two kinds of six-accelerometer allocation schemes and its corresponding formula of SHQMAVIS. Then, measurement errors and installation errors of two accelerometer allocation schemes are discussed and analyzed. The results show that the second six-accelerometer allocation schemes can be used to measuring vibration in SHQMAVIS.
