摘要: 笔者在文中对桥梁板式橡胶支座和铅芯橡胶支座在建立线弹性模型基础上,利用减隔震设计原理对其性能进行理论分析.在指出板式橡胶支座的不足之后,进一步对铅芯橡胶支座的主要参数如初始刚度、屈服刚度、铅芯直径等对其减隔震功能的影响进行了分析.通过分析指出铅芯橡胶支座的优点以及它是如何克服了板式橡胶支座不足的.

关键词: 铅芯橡胶支座, 板式橡胶支座, 减隔震

Abstract: In this paper , The normal rubber bearing(RB) and lead rubber bearing(LRB) are analyzed by applying designing principle of isolation on the basis of linar-elastic model. After pointing out the defect of normal rubber bearing(RB) , the authors mainly analyze key parameters, for example, primate stiffness、yield rigid、lead diameter and talk over the effects by key parameters on Isolated Function. In the end, we point out the advantage of lead rubber bearing(LRB) and how it overcomes the defect of normal rubber bearing(RB) .

Key words: lead rubber bearing(LRB) , normal rubber bearing(RB) , Isolation
