摘要
为提高石英挠性加速度计的量程,分析了石英挠性加速度计量程受限机理,确认电磁反馈力与质量摆质心不重合是加速度计量程受限的主要原因。在此基础上,采用减小加工与装配误差和提高质量摆抗扭刚度的方法来提高石英挠性加速度计量程,并通过样机验证了该技术措施的有效性。
To improve the range of quartz-flex accelerometers,this study analyzes the mechanism affecting this range and confirms that the primary reason for the restricted range is that the center of the electromagnetic feedback force is not superposed on the center of mass of the mass pendulum.Based on the analysis,methods for improving the range are presented by reducing the deviation of mechanical machining and assembly and increasing the torsion resistance of the mass pendulum,the efficiency of which is confirmed by prototypes.
