日本三菱重工业公司的振动台尺寸为15米×15米×2.7米,其规模在世界上是独一无二的。这种设备能做大规模振动试验,它予示着抗震工程显著的进步。另一方面,为了在负荷下使超大型振重台振动,平台本身的强度和振动特性便成为重要问题,并应对它这行全面测定。在详细设计前,为了证实设备的安全,作者进行了各种类型的模型试验和理论分析。本文概述了试验结果及分析。
Japan’s Mitsubishi heavy industry company shaking table size of 15 m × 15 m × 2.7 m, its size is unique in the world. This equipment can do large-scale vibration test, it shows a significant progress in seismic engineering. On the other hand, in order to vibrate a very large vibrating table under load, the strength and vibration characteristics of the platform itself become an important issue and it should be thoroughly determined in this line. Before detailed design, in order to confirm the safety of the equipment, the author conducted various types of model tests and theoretical analysis. This article outlines the test results and analysis.
