Analysis of Earthquake-Resistance Ability for Large Size computers

摘要

The earthquake-resistance ability for large size computer was analyzed by FEM (Finite Element Method) using three-dimensional elastic models. For 19-inch rack computer Frame structures, whether they include contents (equipment and units) or not, the natural frequency, The dynamic frequency response and the dynamic time earthquake response for the same vibration as The earthquake in southern Hyogo prefecture, were calculated. The analysis results were in Agreement with the experimental results, and the vibration properties of the structures were Claeified. Accordingly, it was possible to develop to develop a high earthquake-resistance ability computer Structure at low cost.
