摘要
简要介绍ASHM实验室近两年在基于光纤光栅传感器的大型起重机械健康监测技术、基于光纤声发射传感器的大型起重机械局部损伤监测技术,以及基于无线传感节点的大型起重机械健康监测技术研究等方面所取得的阶段性研究成果,部分研究成果已在现场进行应用试验,效果良好。大型起重机械结构健康监测技术不仅能实现对起重机械结构健康状况进行实时监测,还能及时捕获起重机械结构失效的前兆,预防突发性灾难事故,避免重大人员伤亡与财产损失。
The research advances in structure health monitoring for Lifting Machine in the ASHM laboratory in the past two years are presented in this paper. Three kinds of technologies of structural health monitoring for Lifting machine are proposed based on fiber grating sensor, Fiber-AE sensor and wireless sensor nodes and so on. Part of the achievements are already used, and gained favorable results. The structural health monitoring technologies for Lifting Machine can not only realize real-time monitoring of the structural health condition, but also can get the failure precursor： about structure. It can prevent sudden disaster, and avoid heavy casualties and property losses.
