摘　　要：为了实现空间高微重力主动隔振平台的主动隔振性能,需要精确测量平台振动。首先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,重点研究两种采用六个单轴线加速度计的配置方式及其解算公式,并对圆形配置方式的安装误差作了分析,通过仿真分析验证得到结果表明,六加速度计的圆形配置方式可用于目前研制的高微重力主动隔振平台的振动测量。In order to realize the excellent vibration isolation performance of Space High Quality Microgravity Active Vibration Isolation Platform（SHQMAVIP） , it is necessary to measure the vibration of space science experiment 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 - accelerometcr allocation schemes and its corresponding formula of SHQMAVIP. The installation errors of accelerometer allocation scheme in circle are discussed and analyzed. The results show that six - accelerometer allocation schemes in circle can be used to measuring vibration in SHQMAVIP.
