九子台模拟地震振动台台阵系统及应用

Research on the Shaking Table Array and Dynamic Model Test

地震模拟振动台作为结构抗震研究的重要试验设备之一,从20世纪60年代至今,经历了从线性到非线性、时不变到时变、模拟控制到数字控制、位移控制到加速度高级算法控制的发展过程。与此同时,随着经济、技术的飞速发展,以及抗震研究工作的进一步深入和广泛,地震模拟振动台台阵试验逐渐发展起来。本文介绍了目前国内外地震模拟振动台台阵试验系统的发展现状,重点介绍了九子台(1 m×1 m)积木式台阵系统的技术指标、结构原理,以及对利用该试验设备进行的重要试验,并提出了振动台台阵系统使用过程中值得关注的问题和需要改进之处。

As a main test equipment for seismic study,the shaking table was fast developed in the past forty years, from linear to nonlinear, from tmie-invariant to time-varying, from analog control to digital control, and from displacement control to acceleration advanced control. Meanwhile, with the fast development of economy and technique, also the research of structural seismic is more and more further, and the experimental technique of Shaking Table Array is developed gradually. In this paper, the present situation and development of Shaking Table Array is introduced at home and abroad, on the base of which, the main technical index and structure principle of the Shaking Table Array that composed of nine Sub-shaking Tables（ 1 m x 1 m） in Beijing University of Technology are emphatically introduced. Finally, some important tests completed using this test equipments are summarized, and it put forward the key problems and the improvements in the future using process.
