| 摘 要： | 在地震中，建筑结构可能不会倒塌，但建筑中的浮放设备可能发生滑动、摇晃或倾覆而造成损失．把地震波减化为水平向谐波，浮放设备简化为搁置于刚性平面上的刚体，研究了可能发生的运动状态及其控制方程，并对倾倒的判断标准及物体与基础碰撞的行为进行了探讨．

| Abstract: | With the development of modern engineering technology, a house might survive a seismic event, however, the free-standing equipment in the house could be damaged due to sliding, rocking and toppling. The free-standing equipment was modeled as a rigid body laid on a rigid plane. The earthquake wave was simplified as a horizontal sin-type wave. The dynamics of the object was analyzed. The criteria were discussed for judging the object's toppling and the colliding between the object and the plane. |
