摘要：针对石英挠性加速度计摆片组件的梁易产生断裂的现象，通过分析石英挠性加速度计的工作原理，利用Pro/E分别对石英摆片和铝合金骨架进行了三维建模并装配，然后根据载荷计算在ANSYS中对装配件进行了系统的应力分析，给出了石英摆片组件在实际偏移0.02 mm最大位移下的变形场和应力场，并根据应力场分布提出了石英摆片梁结构的优化方案。研究结果表明，石英摆片组件的最大应力随着加速度载荷的增加保持不变，且小于石英材料的许用应力。

Abstract: Aiming at the fracture phenomenon easily happened on the beam of the quartz flexible accelerometers chip components, through the analysis of quartz flexible accelerometer works, the threedimensional modeling of the quartz chip and the aluminum frame was built and equipped in Pro/E, and the stress analysis of the component was simulated in ANSYS according to the load calculation, the maximum displacement and stress fields were given under the actual offset 0.02 mm deformation on the quartz chip components, then the optimization program of the quartz chip beam was proposed under the stress distribution. The results indicate that the maximum stress of the quartz chip components remain the same increasing as acceleration loads and less than the allowable stress of quartz material.
