摘要
基于网络通讯平台NetSLab,采用Visual Basic语言开发了一个标准化的开放式单层结构远程协同拟动力试验平台NetSLab-SDOF,它由控制中心、真实试验机、虚拟试验机和远程观察器4个模块组成,并通过互联网传输试验控制信号和反馈数据。该平台可以使不同的结构实验室联合进行结构拟动力试验,同时还提供远程用户同步观察试验并获取试验数据的功能。通过桥梁结构的真实拟动力试验及数值模拟试验和网络速度测试,验证了NetSLab-SDOF试验平台的有效性。
Based on the network communication platform NetSLab, a robust standardized platform entitled NetSLab- SDOF has been developed for remotely cooperative hybrid dynamic testing of single story structures. It is composed of four modules, namely control center, physical tester, virtual tester, and remote observer. Utilizing internet based communication technologies, control and feedback data can be transferred among the four modules. This platform not only allows different laboratories to jointly carry out a single structural hybrid dynamic experiment, but also allows remote users to visualize undergoing experiments synchronously and obtain testing results. Successful applications of real bridge structural experiments, numerical simulation tests, and communication speed tests have confirmed the validity and efficiency of this platform.
