【摘要】 石英音叉陀螺是一种微型惯性仪表 ,音叉的结构参数不仅关系到仪表的敏感性、检测精度和稳定性 ,而且决定了其力学性能。抗冲击性能是结构优化的目标之一 ,作者利用计算机模拟音叉在特定运载器载荷环境下的力学行为 ,试验是在 HP工作站上采用 ANSYS/ LS DY-NA通用有限元程序实施的。结果表明 :样机的抗冲击性能高于引用标准 ,能经受 1 0 0 0 0 g的冲击更多还原

【Abstract】 Quartz tuning fork gyroscope is a kind of micro inertial instrument.The shock resistance is an important parameter of its feasibility.In this paper,with two groups of typical drop test results,the mechanical behaviors of quartz tuning fork on the special vehicle under shock load are numerically simulated using ANSYS/LSDYNA general program of finite element method on the HP computer work station.The results show that the shock resistance of the prototype is higher than the cited criterion and it can bear the shock of 10 000 g .更多还原
