Technology for Improving the Range of Quartz-Flex Accelerometers
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.
