本文描述了一种用于单个陈列柜和单个艺术品的辊式隔离装置。隔离装置由两层组成，形成用于二维水平运动的XY运动机构;每层由在垂直横截面中具有圆形-线性组合形状以产生恢复力的轨道、轮子和摩擦阻尼器组成，摩擦阻尼器包括轮子和轴。由于该装置的有效固有周期与质量无关，因此即使对于陈列柜等轻型设备也可以实现长的有效固有周期。进行了振动台试验，显示出良好的隔离性能的设备，并确认在这项研究中开发的分析模型的有效性。
This paper describes a roller type isolation device for individual showcases and individual works of art. The isolation device consists of two layers that form a XY-motion mechanism for two-dimensional horizontal motion; each layer consists of rails having a circular-linear-combined shape in the vertical cross-section to produce a restoring force, wheels, and fiction dampers comprising the wheels and the axles. Because the effective natural period of the device is independent of the mass, a long effective natural period can be achieved even for light equipment such as showcases. Shake table tests were carried out, showing good isolation performance of the device and confirming validity of the analytical model developed in this study.
