高精度石英挠性加速度计对表头稳定性提出了较高的要求,而垂直敏感轴方向加速度对表头稳定性的影响容易被忽视。首先对表头中摆片组件在垂直敏感轴方向加速度作用下的动力学规律进行了研究;然后设计了基于开环阶跃实验的表头稳定性测试方法;搭建实验平台,在重力场中对摆片组件与重力加速度夹角为0°和180°的情况进行了实验。实验结果表明:摆片组件与重力加速度夹角为0°时,摆片摆动幅度小,石英挠性加速度计表头稳定性好。

High precision quartz flexible accelerometer on the stability of the header made a higher demand.The effect of the acceleration in the direction perpendicular to the sensitive axis on the stability of the header is easily overlooked.Firstly, the kinetic law of the quartz pendulum components under the acceleration in the direction perpendicular to the sensitive axis was studied. Then the method of header stability based on open-loop step experiment was designed.By the experimental platform in the gravitational field, the two cases that the angle...
