【摘要】：利用Matlab的强大矩阵运算功能、以及OpenSEES的开源特性,采用混合编程方法,建立了基于MatlabOpenSEES的子结构混合模拟试验系统.详细介绍了子结构混合模拟系统的组成及其原理,即Matlab模块、OpenSEES数值子结构模拟模块以及两者的接口.其中,Matlab模块主要实现运动方程计算、试验子结构加载控制以及数据采集功能;OpenSEES数值子结构模拟模块为子模块,实现子结构的数值模拟分析,供Matlab模块调用;接口可通过读写文本或Socket通信变量实现两者数据传输.该系统可以直接在外接的计算机上编程独立实现,再通过数据采集卡与电液伺服设备控制系统硬件的I/O(输入/输出)通道连接即可,从而避开了设备控制系统复杂的底层编程技术,减少了对控制系统本身的要求,降低了试验难度和费用.通过3个大比例尺结构试验模型的系统子结构混合模拟试验结果,验证了所提出的子结构试验系统的可行性.
[Abstract]:By using the powerful matrix operation function of Matlab and the open source characteristic of OpenSEES, a hybrid simulation system based on MatlabOpenSEES is established by using mixed programming method. The composition and principle of the hybrid simulation system with substructure are introduced in detail. Among them, the Matlab module mainly realizes the motion equation calculation, the test substructure loading control and the data acquisition function, and the OpenSEES numerical substructure simulation module is the sub-module. The interface can be realized by reading and writing text or Socket communication variable to realize the data transmission between them. The system can be programmed independently on the computer directly connected with the outside, the interface can be called by the Matlab module, and the interface can be realized by reading and writing the text or the Socket communication variable. Then the I / O (input / output) channel of the hardware of the electro-hydraulic servo equipment control system can be connected with the data acquisition card, thus avoiding the complicated bottom programming technology of the equipment control system and reducing the requirement of the control system itself. The difficulty and cost of the test are reduced. The feasibility of the proposed substructure test system is verified by the results of the system substructure mixed simulation of three large scale structural test models.
