地震模拟振动台台阵系统是一种重要的结构动力试验设备,其控制技术是国际范围内结构实验技术领域的重要研究方向。文章简要介绍了地震模拟振动台及多振动台台阵系统的历史发展和现状,以北京工业大学九子台台阵系统为例,对振动台台阵控制系统的功能、特点进行了总结和介绍,并重点分析和探讨了多振动台台阵系统控制技术的相关研究与发展。该研究工作对于开展振动台相关控制技术和振动台混合试验技术的研究具有一定的参考价值。

The multiple shaking table array is a kind of dynamic structural test equipment and the control technologies of this system is an important research topic in the field of structural test. The historical development and current status of the shaking table and multiple shaking table array system were briefly introduced in this paper. And then, researeh and advanees of the control of multiple table array were analyzed and dis- cussed. Taking the large-scale shaking tables array with nine sub-tables constructed and installed in the Civil Engineering Experiment Center of the Beijing University of Technology as an example, the functions and fea- tures of multiple table control system were summarized and studied. A certain referenee value of this paper was expected for the related studies of the shaking table control technology and hybrid testing techniques based on the shaking tables.
