Seismic Analysis Method for Cabinets and Other Components of a Process Computer System

A process computer system consists of several cabinets connected to each other. Each cabinet includes many boards and other components. A vibration modeling method for these row cabinets and their internal components for evaluating of the functional capability of process computer systems during earthquakes was proposed, and used for vibration analysis of process computer system cabinets. By comparison of the analytical results with test results, the usefulness of the modeling method was verified. By use of this method, the seismic capability including the functional capability of process computer systems can be evaluated solely by analysis.
