摘　　要：针对微陀螺高精度和微型化的发展趋势,依据振弦式陀螺的工作原理建立了振弦式陀螺频率检测数学模型;应用ANSYS软件分析了陀螺检测结构参数影响,优化了振弦式陀螺整体结构并建立了振动响应仿真分析。结果表明振弦式陀螺驱动结构振动响应随着驱动力的增大,驱动响应位移量也随之增大,且驱动力与位移量之间具有很好的线性关系,可以很好地控制振弦式陀螺框架驱动力,优化振弦式陀螺结构尺寸,从而验证了振弦式陀螺电磁驱动与频率检测方案模型的可行性。Based on the working principle of vibrating string gyro,the mathematical model of frequency detection of vibrating string gyro was established in line with the trend of high precision and miniaturization of micro gyro.Using ANSYS software to analyze the parameter influence of gyro structure,the whole structure of vibrating string gyroscope was optimized and the simulation analysis of vibration response was established.The results show that the vibration response adds with the increase of driving force,and driving force displacement increases,and there is a linear relationship between driving force and displacement.For this reason,the driving force of vibrating string gyro frame can be well controlled and the structure and size of vibrating string gyro can be optimized,verifing the feasibility of electromagnetic-driven vibrating string gyro and frequency detection scheme model.
