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

Time history analysis for investigation of dynamic behavioral characteristics of uninterruptible... 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Structural Integrity and Maintenance Taylor & Francis
