Assessment of Functionality of Medical Appliances Installed in Base-Isolated Hospitals and When Subjected to Vertical Motion

本文研究了医疗器械加速度响应相对于输入加速度的放大机理及其对器械性能的影响。当最大加速度超过4g时，电器将遭受明显的跳跃和相应的损坏。垂直方向上具有柔性元件的那些，其中它们将经历显著的运动，例如即使对于范围为1至2g的加速度也会跳跃。一个通用的三自由度模型的开发，以量化从地面到地板的上部结构的加速度放大的程度。

Examined in this research are the mechanism of amplification for the acceleration responseof medical appliances relative to the input acceleration and their effect onto the performance of the appliances. The appliances would sustain significant jumping and according damage when the maximum accelerations exceed 4g. Exceptions are those with flexible elements in the vertical direction, in which they would experience significant motion such as jumping even for the acceleration ranging 1 to 2g. A generic 3DOF model is developed to quantify the degree of acceleration amplification from the ground to the floor of the superstructure.
