摘　　要：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。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 in space science experiments accurately.The method of measurement of angular and linear accelerations using linear accelerometers was introduced.Two kinds of six-accelerometers allocation schemes were proposed and the corresponding formula for SHQMAVIS was presented.Then,measurement errors and installation errors of the two accelerometer allocation schemes were discussed and analyzed.The results show that the second six-accelerometers allocation schemes is better for measuring vibration in SHQMAVIS.
