【摘要】：本文主要研究在微张力(小于5g,精度?0.5g)状态下如何绕制出高质量的光纤环。光纤环的绕制技术是光纤陀螺仪的关键技术之一。在微张力状态下,光纤环的精确排线变的困难,难以顺利进行,研制出合理的绕制工艺对提高光纤陀螺仪精度是必要的。本文首先研究了光纤环的基本工作原理及其机械性能。在分析了传统光纤环绕制方法在小张力状态下精确排线困难的原因的基础上,验证了拨杆法的理论可行性,进而提出了一套采用拨杆法绕制四级对称光纤环的工艺方法。总结了在拨杆法绕制光纤环过程中常出现的问题,针对问题原因以及解决办法进行了详细的探究。通过实验对拨杆法进行了详细的研究,认为拨杆法的实质是通过二次定位减小缺陷出现的概率,提高缠绕的稳定性。提出了拨杆法对机械系统、图像系统和电器系统的要求。定义了影响拨杆法绕制光纤环的各种因素,并对其进行了定性分析。设计出了一套基于拨杆法和图像系统的光纤环排线均匀度的评价方法。基于现有的光纤和图像系统,均匀度测量分辨率能够达到3%。在大量实验的基础上定量的分析了各个影响因素,提出了度量标准和最优值区间。分析了拨杆法的优缺点,总结了实验中出现的问题并给出了相应的解决方法。最后,为了控制拨杆系统的振动,对拨杆系统关键部件进行了模态分析。
[Abstract]:This paper mainly studies the micro-tension (less than 5g, precision? One of the key technologies of fiber optic gyroscopes is how to make high quality optical fiber rings under the condition of 0.5g). In the state of micro-tension, the precise wiring of the optical fiber rings becomes difficult and difficult to proceed smoothly. It is necessary to develop a reasonable winding technology to improve the precision of fiber optic gyroscope. Firstly, the basic working principle and mechanical properties of optical fiber ring are studied in this paper. On the basis of the reasons for the difficulty of wiring, This paper verifies the theoretical feasibility of the pull rod method, and then puts forward a set of technology method of four-level symmetrical fiber ring winding with the pull rod method, and summarizes the problems that often appear in the winding process of the fiber optic ring by the pull rod method. In this paper, the causes and solutions of the problem are discussed in detail. The method of pulling rod is studied in detail through experiments. It is considered that the essence of the method is to reduce the probability of defects by secondary positioning. In order to improve the stability of winding, the requirements for mechanical system, image system and electrical system are put forward. A set of evaluation methods of fiber ring alignment uniformity based on pull rod method and image system are designed. Based on the existing optical fiber and image system, The resolution of uniformity measurement can reach 3. On the basis of a large number of experiments, the influencing factors are quantitatively analyzed, and the measurement criterion and optimal value range are put forward, and the advantages and disadvantages of the method are analyzed. The problems in the experiment are summarized and the corresponding solutions are given. Finally, in order to control the vibration of the rod pulling system, the modal analysis of the key components of the rod pulling system is carried out.
