【摘要】：光纖是一種高質量的遠距離信號傳輸介質,它具有信號損失小、失真低、傳輸信號速度快、質量高等一系列優(yōu)點,使用光纖進行信息傳輸?shù)囊环N重要用途就是光纖制導導彈。光纖是光纖制導武器唯一的數(shù)據(jù)傳輸載體和通道,用于傳輸下行圖像和上行指令,是光纖制導武器的生命線。制導導彈光纖線包纏繞質量的好壞直接影響武器的可靠性。為了保證不出現(xiàn)光纖跨越、陷入、松弛、跳線、回跌和坍塌的缺陷,以及在飛行放線制導過程中斷纖的現(xiàn)象,因此光纜纏繞中需要使用光纖粘接劑。采用不同形式的施涂工藝,又將導致不同的粘接力,從而對線包的整體質量產生影響。制導光纖高速纏繞過程中自動精密施膠系統(tǒng)的研發(fā)正是針對這一關鍵技術難題展開研究的。本文在對纏繞粘結劑組分及特性分析的基礎上,結合課題針對粘結劑涂敷的具體指標,提出了一種系統(tǒng)的實現(xiàn)制導光纖纏繞粘結劑精密涂敷的方法。對機械系統(tǒng)中的主要部件絲杠螺母副、步進電機、聯(lián)軸器以及霧化噴嘴進行了計算及選型�；诹黧w分析用CFX軟件對霧化效果進行了仿真,并定性給出了相關參數(shù)對霧化效果的影響規(guī)律。根據(jù)噴涂的要求選擇了調節(jié)供氣壓力的元件。結合系統(tǒng)整體的要求,設計了粘結劑精密涂敷的控制系統(tǒng),主要由PLC、步進電機驅動器、壓力變送器、電氣比例閥組成。最后在搭建的實驗平臺上進行了實地試驗,系統(tǒng)基本能夠實現(xiàn)預期的功能。
[Abstract]:Optical fiber is a kind of high quality long-distance signal transmission medium. It has a series of advantages, such as small loss of signal, low distortion, high speed of transmission signal, high quality and so on. An important use of optical fiber for information transmission is fiber-optic guided missile. Optical fiber is the only data transmission carrier and channel for fiber-guided weapons, which is used to transmit downlink images and uplink instructions. It is the lifeline of fiber-optic guided weapon. The quality of fiber-optic wire wrapping of guided missile directly affects the reliability of weapon. In order to ensure that there are no defects of fiber crossing, falling, loosening, jumper, falling back and collapsing, And the phenomenon that the fiber is interrupted in the course of flight guidance, so it is necessary to use optical fiber adhesive in the winding of optical fiber cable, and different forms of coating technology will lead to different bonding force. The research and development of automatic precision sizing system in high speed winding of guided optical fiber is aimed at this key technical problem. Based on the analysis of the composition and characteristics of binder, According to the specific index of binder coating, a systematic method of precision coating of guiding fiber winding binder is proposed. The main parts of mechanical system are the screw nut pair, step motor, and so on. The coupling and atomizing nozzle are calculated and selected. The atomization effect is simulated by CFX software based on fluid analysis. The influence of relative parameters on atomization effect is given qualitatively. According to the requirements of spraying, the elements regulating the air supply pressure are selected. According to the requirements of the whole system, a control system for the precise coating of binder is designed. It is mainly composed of PLC, stepper motor driver, pressure transmitter and electric proportional valve. Finally, the field test is carried out on the experimental platform, and the system can basically achieve the expected function.
