摘要

本文通过三轴振动台试验对不间断电源系统进行了抗震研究。选择符合IEC-60950的100kVA不间断电源系统作为试样。输入加速度时程是基于ICC-ES AC156代码生成的，比例因子范围从25%到600%。根据测试结果，从基频、阻尼比、加速度时程响应、动态放大系数和相对位移等方面对UPS的损伤和该装置的动态特性进行了评估和解释。此外，提出了一个简化的分析模型，并进行了参数研究，以了解UPS的动态特性。

Time history analysis for investigation of dynamic behavioral characteristics of uninterruptible power supply system

ABSTRACT This paper presents a seismic investigation of an uninterruptible power supply system (UPS) through triaxial shake table tests. A 100-kVA uninterruptible power supply system compliant with IEC-60950 was selected as the test specimen. The input acceleration time histories were generated based on the ICC-ES AC156 code, with scaling factors ranging from 25% to 600%. Based on the test results, the damage of the UPS and dynamic characteristics of this device were evaluated and explained in terms of fundamental frequency, damping ratio, acceleration time history response, dynamic amplification factor, and relative displacement. In addition, a simplified analytical model was proposed, and a parametric study was conducted to understand the dynamic characteristics of the UPS.
