摘要:
为解决基于多匝光纤环的盘式光纤加速度计的灵敏度提升问题，本文对其力学特性和应变分布进行了理论分析与有限元仿真。采用体积平均法计算出粘有多匝光纤环的弹性盘的等效参数，进而推导出盘式光纤加速度计的灵敏度和谐振频率表达式。通过有限元仿真软件构建了盘式光纤加速度计拾振结构的仿真模型，分析了理论模型和有限元仿真模型之间的误差来源。实际制作的盘式光纤加速度计的性能参数测试结果与仿真结果接近。本文构建了基于多匝光纤环的盘式光纤加速度计的理论模型和仿真模型，对设计高灵敏度的盘式光纤加速度计具有重要意义。
Abstract:
For the purpose of improving the sensitivity of the fiber-optic flexural disk accelerometer based on multi-turn fiber coils, the theoretical analysis and finite element simulation of its mechanical properties and strain distribution are carried out. The volume-average method is used to calculate the equivalent parameters of the elastic disk with multi-turn fiber coils, and then the sensitivity and resonance frequency of the fiber-optic flexural disk accelerometer are calculated. The simulation model of vibration pickup structure of the fiber-optic flexural disk accelerometer is built by finite element simulation software, and sources of the difference between theoretical model and simulation model are analyzed. The performance parameters of the actual fabricated fiber-optic flexural disk accelerometer were tested, which is close to the simulation result. Theoretical model and simulation model of the fiber-optic flexural disk accelerometer based on multi-turn fiber coils are built in this paper, which have great significance for designing the high sensitivity fiber-optic flexural disk accelerometer.
