Research Progress of Real-time Hybrid Simulation Test Technology Based on OpenSees
摘要
Abstract
Real-time hybrid simulation test technology can not only control the experiment cost and scale,but also ensure the accuracy of test data,which has a good development prospect in seismic en-gineering,among which,OpenSees software has the advantages of flexibility and efficiency,compre-hensive materials and so on,and is widely used as a numerical substructure analysis platform for real-time hybrid simulation test.Firstly,the development history of real-time hybrid simulation test tech-nology is discussed,and the important time nodes of development at home and abroad are sorted out.Secondly,the theoretical basis of real-time hybrid simulation,namely the classification and function of the iterative integration algorithm of real-time calculus are expounded.Then,this paper explores the use of OpenSees software as a numerical substructure simulation and analysis platform,realizes the hybrid simulation test of data interaction between numerical substructure and physical substructure by using OpenFresco with TCP/IP protocol,and introduces the important research progress at home and abroad.Finally,the problems existing in numerical calculation and loading method of servo actuator in current real-time hybrid simulation tests are summarized and the corresponding solutions are given.关键词
