摘要
通过分析光纤光栅测试技术原理,探讨其在大型吊装工程中应用的可行性,比较了光纤光栅技术与电阻应变片测试技术的不同。以实际吊装工程为例,研究光纤光栅串联技术、间断测试技术,最后用有限元分析技术验证测试结果的准确性。
By analyzing the principle of fiber Bragg grating testing technology,the feasibility of its application in large hoisting project is discussed.And the difference of FBG technology and resistance strain testing technology are compared.Taking an actual hoisting project as an example,the series technology and discontinuous testing technology of FBG are studied.Finally,the accuracy of testing results is verified by finite element analysis technology.
