説明

Fault-tree analysis was carried out to evaluate whether CRT displays are capable of maintaining display functions during earthquakes. When considering the possible failure modes, it is necessary to pay particular attention to the vibration of the internal components, such as the shadow mask and electron gun assembly. The natural frequencies and the seismic responses of these components were analyzed to evaluate whether or not the functional capabilities of CRT displays are affected. The CRT display vibration tests were performed using a shaking table, and the functional capabilities of the CRT display during simulated design earthquakes were verified.
