网络化协同结构拟动力试验方法与技术

Networked Collaborative Structural Pseudo-dynamic Testing Method and Technology

基于网络结构实验室的概念,以湖南大学为首的研究团体开发了用于远程协同试验的网络平台,称为NetSLab.针对土木工程结构试验中广泛应用的MTS控制系统,应用外部命令控制方法,完成了NetSLab网络平台和MTS控制系统的通讯接口,建立了远程协同结构试验系统.以多跨桥梁结构为试验对象,湖南大学、哈尔滨工业大学和清华大学合作,进行了国内首个远程协同结构拟动力试验.试验结果表明,NetSLab平台在互联网上通讯顺畅,MTS控制系统与网络平台能够准确地进行数据传输和协同控制;多个单一结构实验室可以通过互联网整合成为功能强大的网络结构实验室,实现试验设备的远程共享,为进行更为复杂的子结构远程协同试验提供了试验平台.同时,也为建立我国远程协同结构试验示范网络体系提供了基础平台.

Based on the conception of networked structural laboratories,NetSLab network platform for remote collaborative pseudo-dynamic testing has been developed by a research group lead by Hunan University.Aiming at MTS system widely applied in structural testing,external command control method was studied to implement the communication interface between NetSLab network platform and MTS system,so that the remote collaborative structural testing system was set up.The first remote collaborative structural pseudo-dynamic testing in China's Mainland was carried out about a multi-span bridge by collaboration of Hunan University,Harbin Institute of Technology and Tsinghua University.The result manifests that NetSLab platform communicates smoothly on Internet;data transmission and collaborative control can be implemented accurately between MTS system and network platform.Several single structural laboratories are integrated into a networked structural laboratory with powerful function by Internet,which achieves remote sharing of testing equipments,and provides a platform for more complex substructure pseudo-dynamic testing.At the meantime,it also provides a base platform to set up demonstration network system for remote collaborative testing in China's Mainland.
