摘　　要：为了提高陀螺转子组件的动态性能,采用计算机辅助工程(Computer Aided Engineering,CAE)技术考察了某陀螺仪陀螺转子组件结构的模态响应以及应力响应,对陀螺转子组件结构进行了轻量化设计,并对优化前后陀螺转子组件的动态性能进行了仿真和试验结果的双重对比分析.仿真结果表明:优化后陀螺转子组件的模态频率相比优化前陀螺转子组件的模态频率提升较大,前4阶模态频率平均优化率达到了27.5%;优化后陀螺转子组件的最大应力值相比优化前陀螺转子组件的最大应力值显著降低,其中沿X轴向加载时的优化率为41.1%,沿Z轴向加载时的优化率为54.6%.试验结果表明:优化后陀螺仪的正交摆性引起的漂移Y_(1)和轴向质量不平衡引起的漂移Y_(2)相比优化前分别提升了63.0%和84.3%.仿真结果与试验结果具有一致的评价,为动力调谐陀螺仪的产品开发和可靠应用提供了重要支持.In order to improve the dynamic performance of gyrorotor assembly,the modal response and stress response of a gyrorotor assembly structure were investigated by computer aided engineering(CAE)technology.The lightweight design of gyrorotor assembly structure was carried out,and the dynamic performance of gyrorotor assembly before and after optimization was compared by simulation and test results.The simulation results showed that the modal frequency of the optimized gyrorotor assembly increased significantly compared with that of the pre-optimized gyrorotor assembly,and the average optimization rate of the first 4 modes reached 27.5%.The maximum stress value of the optimized gyrorotor assembly reduced notably compared with that of the pre-optimized gyrorotor assembly,in which the optimization rate was 41.1%along the X axis and 54.6%along the Z axis.The experimental results showed that the drift Y_(1)caused by the orthogonal pendulum and the drift Y_(2)caused by the axial mass imbalance of the optimized gyroscope were 63.0%and 84.3%higher than that of the pre-optimized gyroscope,respectively.The simulation results were consistent with the test results,which provides important support for the product development and reliable application of the dynamically-tuned gyroscope.
