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

本研究探讨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医疗器械性能的影响。当最大加速度超过4g时，这些设备将承受明显的跳跃和损坏。例外情况是那些在垂直方向上有弹性的元素，即使在1到2g的加速度范围内，它们也会经历明显的运动，比如跳跃。建立了一个通用的三维模型来量化从地面到上层建筑的加速度放大程度。

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.
