Wheel Winding Type Tensile Test Equipment of Optical Cable

光缆的拉伸性能是影响光纤通信质量的一个重要方面。结合装置需求单位的测试要求,研制了一套轮盘绕线式制导光缆拉伸测试装置。首先阐述了测试装置的测试原理和总体组成,详细研究了测试系统的机械结构、测控子系统、软件系统等功能模块,并利用该装置进行了截面积为0.25 mm^2光缆的拉伸测试实验。研究表明,轮盘绕线式拉伸测试装置可以自动测量计算出制导光缆拉伸过程中的负荷、位移、变形、应力、应变等参数,并实现负荷-变形、负荷-位移、负荷-时间、变形-时间、位移-时间、应力-应变等6种关系曲线的实时动态生成,具有较好的测试精度和稳定性。该装置已投入正式使用,满足使用单位进行制导光缆拉伸测试的各项要求。

Tensile property of optical fiber cable is an important factor which can affect the quality of optical fiber communication. According to the test requirements of an institute for the equipment, a wheel winding test equipmentis developed to test tensile property of optical fiber cable.Test principle and constitution of the equipment were firstly introduced. Then mechanical structure, control and test subsystem and software of the equipmentand other functional moduleswere studiedin detail.Afterwards a tensile property experiment of a 025 mm^2cross section area ofoptical fiber cable was successfully performed with the equipment.Study shows that tensile property parameters （load, displacement, extension, strain, stress, and etc.） can be automatically tested with good accuracy and stabilityby the equipment, and six relation curves （load extension, load displacement, load time, extension time, displacement time and stress strain） can be dynamically drawn timely. The test equipment has been used in an institute and met allthe requirements of testing optical fiber cable well.
