摘　　要：静电悬浮加速度计是进行空间飞行器准稳态非重力精密测量的设备。静电悬浮加速度计研制中,需要借助高压悬浮来完成其功能和部分性能评价的相关工作。文章就地面静电悬浮加速度计检验质量高压悬浮中涉及的相关问题进行了理论分析,给出了地面悬浮原理、高压电路实现形式、工作点选取、稳定性控制、高压静电力作用分析等,给出了实际试验结果,表明地面上系统在O.1 Hz附近具有10-8gn/Hz1/2左右的分辨率,并可在悬浮状态下,完成功能及相关性能测试,获得静电悬浮加速度计地面直接性能评价受限的主要因素,同时就存在的问题进行了讨论。The electrostatic suspension accelerometer is a quasi steady and non gravity precision measurement equipment for spacecraft.In the development of electrostatic suspension accelerometer,the evaluation of the functions and the performances of the accelerometer need to be accomplished by the high voltage suspension.On the ground tests,the theoretical analysis of the electrostatic suspension accelerometer related issues involved in the high voltage suspension was carried out.The ground suspension principle,a high-voltage circuit,chooses the working point,control stability,and the high voltage static electricity effect analysis etc.were given.The system resolution near the 0.1Hz is about 10^（-8）g/Hz^（1/2） on ground test,and can finish the function and related performance tests in the suspension state.The main factors of the direct performance evaluation of the electrostatic suspended accelerometer on ground were obtained,and the related problems were discussed.
