UUV惯导系统产生的多线谱振动，对自身探测系统性能、声隐身性能等产生较大的不利影响。针对UUV惯导系统承载结构，分别研究基于超结构的陀螺仪隔振基座设计和系统减振设计方法，开展多线谱抑制优化设计仿真。在保证导航精度的前提下，实现对多线谱的有效抑制。验证了基于超结构的惯性导航陀螺仪多线谱抑制方案的可行性，为下一步完成UUV惯导系统减振降噪结构的制备、集成与试验验证奠定了基础。
The multi-line spectrum vibration generated by the UUV inertial navigation system has a significant adverse effect on the performance of its own detection system and acoustic stealth. Aiming at the bearing structure of UUV inertial navigation system, the superstructure-based gyroscope vibration isolation base design and the system vibration reduction design method werestudied respectively, and the optimization design of multi-line spectrum suppression was carried out by computer simulation .When ensuring the accuracy of navigation, the effective suppression of the multi-line spectrum is realized. The feasibility of the superstructure-based inertial navigation gyroscope multi-line spectrum suppression scheme is verified. It laid the foundation for the next step to complete the preparation, integration and experimental verification of the vibration and noise reduction structure of the UUV inertial navigation system.
