Optical Fiber Dynamie Release Force Test System Research

At high speed, long distance fiber-optic guided missile research and development process, how to guarantee smooth release fibers under conditions of strong pulling force and continuous fiber-optic, this is a solved key technology in fiber-optic guidance technologies necessarily. To overcome this critical technology, we must study the time measurement of fiber relief forcein optical fiber release testHigh-speed optical fiber release force real-time testing system is part of the ground simulation of optical fiber release device.it can be used to testing high-speed release force changes in real time when optical fiber release test, and analyze test data、processing test data. In the optical fiber pelease process, due to fiber breakage problem and optical fiber is not smooth, so we need to study the size of the relief force change.Optical fiber release force is is an important mechanics parameters of optical fiber release test,with the general method is difficult to measure, it is necessary to design a system to measure the release force and study the variation in the optical fiber release of the test. Through the analysis of the test results, the optical fiber release may be improve optical fiber release efficiency.This paper presents a dynamic testing system based on labview platform of optical fiber release relief force.The system consists of hardware sensors, amplifiers,data acquisition cards constituted for the host computer to computer software consists of a test system.This paper describes the features and liberation force and measurement principle.Required hardware choices and writing software. With relief force labview platform real-time data acquisition and preservation of historical data read function of the measuring system. To measure the dynamic relief force proposed solutions.Finally, using the software program of measurement system designed for the static calibration experiment of tension sensor. The static calibration experiment of tension sensor illustrates the feasibility of the design scheme.
