dc.description.abstractStructural failure of a rack due to vibration could result in injury to people, damage to IT equipment, or interruption of services that depend on proper functioning of the IT and networking equipment in the rack. In this topic, a computational study of an IT rack and a group of racks placed adjacent to each other under three vibration load scenarios: transportation, office and earthquake vibration is presented.Each rack can weigh as much as 1600 kg (3500 lb.) when fully populated with IT equipment. Two standards commonly used for testing racks with synthetic seismic loads are the GR-63-CORE Network Equipment Building Systems (NEBSTM) and the International Building Code (IBC). In this paper, the earthquake, office and transportation vibration loads as given in GR-63-CORE are applied on a computer-aided design (CAD) model of the rack mentioned above. The material used is ASTM A36 / A572 series steel. The IT equipment was made in CATIA V5 / Solidworks and then imported into ANSYS Workbench where it was meshed. After meshing, a pre stressed Modal Analysis was run to find the natural frequencies of the body. From the output result of Modal analysis, all modes of vibration were included as input for Response Spectrum analysis (RS-analysis), as those modes will be the dominant modes for vibration. Harmonic Response is used to analyze office vibrations, as the swept sine wave (Harmonic Response) resembles office environment vibrations. Random vibration analysis is used for transportation vibration. All the acceleration curves and standard for testing are in correlation with GR-63-CORE NEBSTM standard. Other boundary conditions included is that the M8 screw used to bolt the bottom of the IT equipment.
