采用ABAQUS对铅芯橡胶支座进行模拟分析,研究支座在极限压剪状态下的应力分布,分析表明:极限压剪状态下钢片层中的拉应力S11和S22、压应力S33及切应力S12对钢片层Mises等效应力的影响较大;支座有效承压区内大部分钢片层中有部分区域的Mises等效应力超过了其屈服强度,产生了屈服;支座内部各橡胶层的Mises等效应力较小,橡胶未发生破坏。 The ABAQUS simulation analysis of the lead rubber bearing was carried out to study the stress distribution of the bearing under the condition of ultimate compression and shear. The analysis showed that the tensile stresses S11 and S22, compressive stress S33 and shear stress S12 has a significant effect on the Mises equivalent stress of the steel sheet. The Mises equivalent stress of most of the steel sheets in the effective bearing zone of the bearing surpasses the yield strength, resulting in yielding. The rubber inside the bearing Layer Mises equivalent stress is small, the rubber did not occur damage.
