【摘要】：本文主要研究在微張力(小于5g,精度?0.5g)狀態(tài)下如何繞制出高質量的光纖環(huán)。光纖環(huán)的繞制技術是光纖陀螺儀的關鍵技術之一。在微張力狀態(tài)下,光纖環(huán)的精確排線變的困難,難以順利進行,研制出合理的繞制工藝對提高光纖陀螺儀精度是必要的。本文首先研究了光纖環(huán)的基本工作原理及其機械性能。在分析了傳統(tǒng)光纖環(huán)繞制方法在小張力狀態(tài)下精確排線困難的原因的基礎上,驗證了撥桿法的理論可行性,進而提出了一套采用撥桿法繞制四級對稱光纖環(huán)的工藝方法。總結了在撥桿法繞制光纖環(huán)過程中常出現(xiàn)的問題,針對問題原因以及解決辦法進行了詳細的探究。通過實驗對撥桿法進行了詳細的研究,認為撥桿法的實質是通過二次定位減小缺陷出現(xiàn)的概率,提高纏繞的穩(wěn)定性。提出了撥桿法對機械系統(tǒng)、圖像系統(tǒng)和電器系統(tǒng)的要求。定義了影響撥桿法繞制光纖環(huán)的各種因素,并對其進行了定性分析。設計出了一套基于撥桿法和圖像系統(tǒng)的光纖環(huán)排線均勻度的評價方法�；诂F(xiàn)有的光纖和圖像系統(tǒng),均勻度測量分辨率能夠達到3%。在大量實驗的基礎上定量的分析了各個影響因素,提出了度量標準和最優(yōu)值區(qū)間。分析了撥桿法的優(yōu)缺點,總結了實驗中出現(xiàn)的問題并給出了相應的解決方法。最后,為了控制撥桿系統(tǒng)的振動,對撥桿系統(tǒng)關鍵部件進行了模態(tài)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.
