一种新型三维隔震支座的试验研究
Experiment On a Novel Three-dimensional Isolation Bearing
摘要
Abstract
The intention of this paper is to research the mechanical properties relationship between the three-dimensional isolation bearing and the two-dimensional isolation bearing. The new disc spring transformed from the traditional one consists of the vertical isolation bearing by a stacking way. And the vertical isolation bearings and the LNR are combined into a novel three-dimensional isolation bearings. Tests about the horizontal and vertical mechanical properties of the LNR, the disc spring vertical isolation bearing and the 3D isolation bearing were carried out respectively. Analyses were conducted on the relationship of the mechanical properties between the 2D isolation bearings and the 3D isolation bearings under independent conditions. Test results show that the vertical stiffness of the disc spring vertical isolation bearing varies linearly with the increase of compressive stress. And the frequency has little effect on the vertical stiffness of that at low frequencies. The horizontal stiffness of the 3D isolation bearing is slightly lower than that of LNR in the independent state.The effect of LNR on the overall vertical stiffness of 3D isolation bearings is not significant.关键词
